Hi Brooke,
You have to understand, on a deep level, that your BF was NOT punishing you. Some people are very sensitive and will run and hide at the first hint of abuse. What he did was actually pretty healthy.
Another thing to keep in mind is all relationships have Honeymoon periods. When you blacked out and called him names, he might have thought, “Finally I am seeing her shadow side and it doesn’t look good. Deep down this girl is bat-**** crazy!”
The only way to truly move on is to vow never to touch alcohol again. Get yourself in a support group. He didn’t deserve to be called idiot and loser just because you can’t handle your liquor.
Best,
Inky
