I broke up with her but I want her back?

3 and a half years? I'm sure she misses and loves you as well, just give it time. My advice is the next time you have a problem with her, talk it out out. Don't do or say something that your going to regret. Example, breaking up with your girlfriend. Write her a letter, inbox her on facebook, text, do something, and tell her whats on your mind. Do it today.....

What does that mean? "she was letting certain things happen"? Don't be such a ***** whipped str8 boy. Already a week after the break up, you can't stand it. You've been together 3 years non-stop. I'll bet you don't even know who you are. You went from mommy to your girlfriend. You should take this time to figure out who you are and to be your own man.

It's hard to answer this without knowing what certain things she was doing that caused you to break up with her in the first place.

Give it some time. Three years is a long relationship. You are used to being with her, and it will take a while to get used to being without her - but don't take that to mean that you shouldn't have seperated.

Ever heard the expression the grass is always greener on the other side? This applies here. You must have had good reason to break up with her, they just don't seem as valid now that you have actually done it.

Give it some time. Your head needs to sort itself out. After a while, things will become clearer, and you will know whether or not you made the right decision.

let go of her for some time, u will eventually know the real feelings. Dont rush anything, if is yours, is yours, no worries. if later u still feel so, u shud go back for her. if she didnt change, then u should just walkthrough, she dont suits you. there is a better one outside. trust me!
