hiya Chole, welcome to the forum - I hope you will like it here.
Suggestions as to the 'little things' are really difficult to give but special attention given to the small things should be a daily 'core'. Stick a memo on the fridge with 'i love you' on it, or send her an old fashioned picture postcard with some sweet message on it, phone her around the time you know she had lunch and ask if she has eaten and what. Order tickets to some show you know she likes without her knowing about it until the moment you stand in front of the entrance. Etc. Etc. Etc.....
