Married and still have strong feelings for ex

I've been married for 2 years I ran into my ex at the casino a few months ago after 9 years. My ex and I dated in college for less than 3 months and then he broke up me and left school. When asked, he said he was having some problems at home and didn't want me involved. I know our relationship was brief but when I saw him again old feelings re-surfaced, feelings I didn't know were there. He is so fine now and at the time I was having some marital problems but everything with my marriage is fine now but I can't stop thinking about my ex. My ex said that he's not going to disrespect my husband and I don't want him too. I just need to let go of him and can't. It's like I'm curious..I think about how things would have been if were still together. Our lives are so different now. I'm married with two beautiful children and he's single with lots of friends. He also doesn't trust himself and shys away from me because he doesn't want to see me hurt. I have a good husband but how do I get over my ex. I would like to see him again but he said no. I keep telling myself I need to see him to get over him. I don't to risk losing three for one. I miss him so much and I don't even know him anymore. sounds crazy I know. I guess I'm grieving the loss of him and accepting the fact that we can't be together right now. I mentioned to him about not communicating anymore but he wants to be friends and I agreed. I told my husband that I ran into him and he said it's up to me if I want to continue talking to him but I have to respect boundaries. I'm stuck on something I can't have, don't need, and don't know how to move on. its hurts so bad. Yesterday I told my ex that I think my feelings are stonger than his and its best if we stop talking. He said he understood. Although I felt like I gained some self control back, I'm still hurting inside. any advice, please help

You did the right thing. I know it is hard to give up someone you love so much. we are on the same page there. You have a family and a good husband and kids. You deserve to be happy with a family. You shouldnt gamble what might have been.

Thanks I needed to hear that but I still can't understand why my feelings were so intense for him. Maybe its how we broke up, my trust issues with my husband or me just feeling sexually frustrated or all of the above. But its not about me anymore at least that's what I keep telling myself for my kids sake. You know this would be easier if he wasn't so fine and didn't live like 15 minutes away. But I know its not worth it. I need to snap back into reality and move on. God give me strength LOL!
