Ex doesn't want a relationship but is still in love with me???

Well I'll try and keep this as short as possible even though my story is quite long I'm afraid to say haha
I was with my ex for about 10 months. We had an argument one day based on absolutely nothing (I started it) And I broke up with him in anger. It was online aswell which annoyed me even more.
Over the next week we were talking about getting back together and working things out. Then one night, out of jealousy and curiosity, I logged onto his email account and saw and email of him exchanging numbers with a girl, which obviously drove me INSANEEE.
I confronted him about it in quite a bad way, I was unbelievably upset and angry because I though he'd asked another girl for her number whilst we were trying to work things out. Well after that he decided that he couldn't take the relationship anymore and he just needed time to himself (Which I can understand because I treated him badly at times and took him for granted) I did the usual begging and nothing worked. So we didn't speak for about 2 months. Then one day we emailed back and forth and exchanged new numbers, we ended up having a 4 hour conversation and everything was nice, he told me he still loved me and all the rest of it.
I visited him a few times after that and slept with him, which I know was wrong. I mentioned to him about getting back together and he said he would atleast think about it. So he did, and he came to the conclusion that we would date and see how it goes. No sex, just straight dating and hanging out. We did that a few times and everything was great. He then saw me 'flirting' with someone on my facebook page (Was just friendly banter) and he got jealous and obviously hated it. After another few arguments he decided he just couldn't do it anymore and wanted to remain friends. So now I'm back to the beginning. Honestly we had an amazing relationship and he was the most amazing boyfriend I could of asked for. I took him for granted and treated him badly at times and it got to him. I know he's in love with me because I can just see it when we're together. He claims he doesn't want a relationship right now because of his studies and all the stress but maybe a few months or years down the line he thinks we could work it out.
He say's I'm the one he could see himself marrying and mothering his children, he just needs some time to himself. He's even broke down in tears infront of me because he's so confused.
Now we're both kind of playing games with each other and trying to act like we're just 'friends' but it's not working out to great.
What should I do? -_-

Btw, there was a pregnancy involved also but ended in miscarriage and it really affected him.
It's also been over 4 months since we officially split and I've realised my faults and all what went wrong with the relationship.
I can honestly say the break up helped me alot and made me realise where I was going wrong. But still I love him far too much just to let him go.

Another thing, I'm not sure if I should show him that I've realised my mistakes and that I've changed and matured, or if I should act distant like the whole 'A man always wants what he cant have' Sort of thing?

i wonder why people get so confused. i have a similiar thing happening to me now except our relationahip was great(no one took one each othe rfor granted). but alas my ex gf is confused and just wants to be single but sees us married in the future. i dont get people. if your in love with someone how can you deny it? she actually told me she is trying to not be in love with me. lol

anyway i say give him the space and move on and in time everything willwork out even its not with him. i know its hard because i dont want to face moving on myself but i know i cant wait years to find out what she wants.

do take your time to heal properly though or youll just be in a rebound relationship. good luck

Well ALOT has happened since I posted that. He decided that he wants to be in a relationship now and we're trying to work on our issues before we properly get back together. Our relationship was great too, but tbh jealousy was a big issue for us and it's something I'm trying to work on right now.
I don't mind waiting obviously, because it's for him. But is there anything I could do or say to speed this whole 'dating' process up so we can be together sooner?
Feel like we're wasting precious time.

As for your ex girlfriend, I'd say the same as what you did, just give her some space but make sure she knows that you love her and want to be with her. If she really does love you then she'll come back. The whole 'acting distant' to get your ex back didn't work with me at all, in fact it drove my ex further away because he couldn't take it. it was only when I made damn sure that he knew how I felt that he started to come around.
She's just having doubts. x

dam this seems like the same relationship problems im having, except im the guy and took her for granted a little since she said she would never break up with me, well were on a break, she has a boy toy, and i still love her.
She broke down crying in front of me also and said how much she loves me and just needs some time to get this out of her system, i hate waiting though and i miss her so much and do love her, she even said just like ur bf said, that she sees me being the father of her kids and being the guy she wants to spend the rest of her life with, but right now needs time, this sucks i miss her a lot :/

I'm saphire btw, just in case you thought it was weird me replying to this lol.

Yeah I just don't get my ex, we were working things out, on the verge of getting together then one day we have a little disagreement over something silly and now he's just distant again. We've basically gone back into the 'friend zone'
I have no idea how he can just switch his feelings off like that.
I don't know whether it's because he really just Inst bothered or because he's being stubborn. (We're both extremely stubborn people)
To be honest I've just gave up now, I've spent 5 months waiting and all just to go back to the 'friend zone'
The only form of communication we have now is actually through the Internet. I find it hard to talk to him just as friends so I'm not sure if I should delete him or not? And just try get on with things.

& I think you should make sure she completely knows how you feel. Apologize for taking her for granted and just basically give her a little space.
I think this 'toy boy' may just be a rebound.
& I know exactly how you're feeling, I wouldn't wish this upon anyone.
I suppose we just need to give them both time. Easier said than done, I know.
You can private message me if you ever need to talk

yea i hope i can work something out because i dont want to wait that long for nothing like i feel that she does love me but idk maybe she just needs time to miss me idk
