Do I get back with my girlfriend?

First of all, stop dumping her n getting back n dumping her n getting back...that alone is an ugly cycle. You know you want get back with her, so why even ask. Get back with her. Now about her drinking problem, if you really care for her don't let her be in situations in which she's gonna get wild with the al-kee-hawl. So, plan your weekends with her. For example, get back with her now and this weekend take her to the movies, and restaurant and go home and have fun at home, just you two. The next day, stay home and watch movies and if she wants to drink go buy some alcohol but don't buy it in excess just enuff to have a good time. The following week do something else that doesn't include drinking, or minimal drinking, but YOU be in control of the amount. That way you help her and you help yourself be responsible and all those things that make you feel good. BUT! Only get back with her if you're gonna be willing to work with her so you can stop your "dumping her" cycle. Now, don't feel bad about you getting wild the weekend you were broken up. See it as a little celebration because you were single. No biggie. So, yea. Good luck with that buddy! *cheers!*
