I don't know what to do!

Okay so my bf and I have been dating for almost 2 years. He's probably the only person that 'gets' me. I'd do anything for him; as will he. We've had our ups and downs but I always thought we make make it through whatever. We've broken up before but the longest was a month. So we've been arguing a lot and this morning I left him. He broke a promise he made me for the 5th time!! I told him I couldn't handle yet another broken promise. When I said it I thought I'm gonna go through with it. But the thing is I still believe that we have a chance. But he told me that we can never get back together because he doesn't trust that I'd be there for him. He has doubts now because I told him I didn't want to be with him.
I really need advice.. No one understands what I'm going through because they think I'll get over it & that I'm too young. But I really do believe he's the one.
Help me =( !!

If you really believe he is the one, then why did you break up with him? (and not for the first time)

It's obviously not working; it doesn't sound like a healthy relationship at all to me. So my advice is to let it go. You broke up with him (again), it's probably best to leave it that way. It will hurt temporarily, but it's better in the long run.

Thank you all for your advice. Appretiate it.
I decided to give it one last shot, we've come so far I'm not giving up now eventho I was the one to break up with him. The break up was to teach him a lesson..
Again thanks everyone xx

^Agreed. Drop him for good.

^^Agreed

One also has to think of what"promises" are being broken and learn to fight the right battles. Not every promise someone makes you is going to be kept, if you are going to punish everyone who breaks a promise by casting them out of your life, you may want to work on your view concerning relationships and their importance.

Thank u all :)

Sit with him and talk honestly, set free what's inside you both..
