Is it me or the disease talking?

My husband told me I’m the reason why he drinks so much. That I’m stressing him out so much that he has to drink. Yes we have are disagreements & arguments & I struggle with my Borderline personality disorder but I’m trying to get better & I find it unfair he’s blaming me for his drinking even tho he drank a lot before we got together & even when we first got together till now....
