Me [23 M] and my [22 F] together for almost 2 years, just broke up last monday and I can't stand being without her.

I was just broken up by an amazing girl this last monday. We've had an on/off relationship for about two years, so I would say that technically we have be together for something like 21 months. In the past we have broken up 4 times, the last being this week, which I realize is not healthy. 3 of those times it was because she was drunk and was acting IMO, very irrationally, for example breaking up the night of a sudden problem, sometimes minor, that occured that night. I've told her that the only reason that we have broken up is largely because she doesn't make the best decisions when she is drunk, and I know she has been working on drinking less. I will not say that it is 100% all on her though, and that I am sometimes at fault too.

It took us about a week to a month each time to reconcile our relationship, but this time things are looking worse.

This time, she broke up with me very suddenly on the 15th because of my lack of communication with her, especially because she has been very depressed lately. I entirely agree with her on that subject, as she has told me this before, and I have been working hard at that going out of my way to try and work on it for a while just so I could talk to her in a more deep (sorry for lack of a better word) way. I told her that, but she said that she needed to be alone to work out her depression, but I want to help her through it.

I love this girl very much, I can picture a future wither her and I would do anything to repair our relationship. Could anyone give me some advice? Thank you.

tl;dr: A girl and I broke up because of her depression and my lack of communication and I would like to repair the relationship.
