I'm getting crazy hereeeeeeeeee.. help?

i've been in this situation before. i know how it feels to think that this guy could be "the one" and if you let him go then you won't find the love of your life. I've also been on the other end... leaving then coming back a million times. First, it sounds like he's mostly with you for sex. That probably isn't true though, just an observation. If you really want you and him to last, you need to make it clear to him that this is his last chance to be with you and if he leaves again, when he comes back you won't take him back. Otherwise, this will go on forever. If a guy is not committed after 2 years with you, even with many problems, then there's a very slim chance of that relationship lasting. If he won't listen to you when it comes to commitment or when you talk about how he treats you, then you can do much better. You will find someone great one day, whether it's him or not. Best of luck to you! Stay strong!
