Here are my two:

I became interested in this girl because she was gorgeous, funny, smart and motivated in life. I was a sophomore and she was a freshman in college. I'd recently been hospitalized after taking drugs which almost killed me, but campus police didn't care because I saved my own life by calling an ambulance.

Anyway, I agreed to try dating her after making sure she knew that I was I'm a weird place and probably wouldn't be able to maintain my own happiness while being in a relationship. She was very understanding and accepted that, no matter what, we would make sure we would still be friends at the end of it.

• she once almost broke down my dorm room door while being restrained and yelling FUCK (name) because I only made her cum 3 times, after guilting me into having sex again.
• she tried to convince everyone I knew that I only used girls for sex and then body shamed them
• she befriended the room above me and would bounce basketballs while drinking with them until 4am to keep my up
• she banned any of her friends from talking to me and would attack them if they did
• she pretended to be friends with my friends just so she would have an excuse for telling them not to talk to me anymore
• tried to call rape, failed (luckily she had attacked enough of her friends for talking to me for her to lose credibility)
• she would guilt me into having sex with her because I "wasn't trying hard enough to maintain the relationship."

The other girl, who happened my senior year of high school attempted suicide after a month of being miserable with each other and telling her that I didn't want to be involved with a pathological liar who threatens suicide to keep me in her life. Turns out she had an ounce of truth in her.

My sister was raped by her ex boyfriend who did nothing but tell her she was a failure and a loser for thinking she was worthy of breaking up with him (shed attempted suicide twice in the relationship and he blamed both times on her inability to make her happy)

My brother was harassed by a girl pretending to be pregnant after breaking up with her after her emotional abuse before he went abroad to escape her for a semester.

People are exes for a reason. If you're not happy Ina relationship and the other person refuses to admit any fault or responsibility in mutual unhappiness, move on to hat ever makes you happy. You have a life to live and it's your responsibility to make that life as beautiful as possible for the people you care about. Especially if that means leaving them alone. Because clearly shit isn't working.
