I got very constructive and intelligent feedback, I appreciated it and reflected upon it. Thanks to all.
I do have an alcoholic dependency as I'd drink every day to the point of getting drunk. This didn't affect my academic performance or social interactions to be honest. But psychologically I was wrecked.
It was difficult to financially support someone. And I had to take care of her I was obsessed of the idea of fixing both our lives.

About myself I took the right steps. I took measures of getting therapy and adjusting my meds. Going to gym, working atm, and pampering myself. And with time trying to heal with the trauma. The only scar I have is that I'm not able to trust anyone or let anyone get close to me and I'm cold with people, not as social as how I used to be.

In general I got mixed replies. My psychiatrist that's treated me for years told me it was her romantic feelings/expectations that ruined it. And my history of abuse caused me to lash out. I didn't mean to hurt her, I did initiate it that day yes but I did not leave a mark on her and I felt provoked. She, OTOH, left deep bite marks on my shoulders and arms that left me bruised and I still have the wounds.
We both protected each other when it came to the uni/cops. Tho she did threaten me later that she'd change her statement. I did accidentally get my hand stitched by breaking a bottle once after we had a fight.
Some would say it was my fault entirely and then that would make me feel guilty.
