Dt121, I'm so sorry you're going through this with your BF. Life with an addict is hard, but you're in the right place here, you're not alone.
I agree with what atalose said: We can only support them so much before we begin to notice we are losing ourselves along the way and getting just as lost in their addiction.
When does your BF come home from abroad? I would use this time to really take care of yourself and decide what you want from your life. Read all you can about alcoholism and addiction. I personally have gotten a lot of our my local Al Anon group, it's free, anyone can go, pick a meeting and attend.
Thinking of you!
