He is making me fall apart? I really need some advice?

Now first things first, let's get some things straight. You say "he got you drinking"!!!! Now what do you mean? Did he actually force you to drink? Please sweetie, when you get drunk, it's nobody else's fault so don't blame it on others. Please, take responisbility of your actions and decisions. Also you say that you don't want to break up with him but should you? So, whatever I write here is useless, right? Of course you should break up with him, the guy is immature and does not want to be committed. Please do not be offended and I do not mean to sound so harsh, but I just hate it when people do not take charge. I really wish you the best and it seems that you are a loving person and you deserve better than this, so why are you settling for less?
