I'm so sorry he betrayed you again

I'm not an alcoholic, but my experience with them is that the alcohol gets rid of their inhibitions and they say and do exactly what they WANT TO, but CAN'T do sober. My ex's mom (alcoholic) she always said, 'a drunken person speaks a sober mind' and her other favourite, 'pour for courage'. I found out on occassion what she and others REALLY think of me, needless to say, I cut off all contact. Now, idk maybe this is not the case with your bf, maybe he's not got the hots for that girl, but alcohol convinces him he does or changes his personality completely (remember, I'm not an alcoholic, I'm speculating on it's effects) If that is the case then there is hope for you 2 yet

Well even if he falls under the former, it could also work, but I wouldn't want a bf that had the hots for someone else, wether he acts on it or not, so it's entirely your choice. ANYWAY, I'm rambling again, Nina, I hope he get's help, and I hope you finally get your happiness, you are deserving and worthy.
