<human>: Hey, I'm new to this subreddit so please forgive me for any formatting errors.

So basically I've been dating this girl for nearly two years. Everything was going great up until about 9 months ago. Her Mom decides that I am too similar (in vague/ambiguous ways) to her ex-husband who was abusive. She tells my girlfriend to leave me. My girlfriend tells her mom that she will but continues to date me without either her mom or I knowing the full situation. Eventually I find out her parents don't know we're still dating, and we've been in sort of a limbo for the past few months.

The problem is this: we both wanted to date each other but her mom is/has been  emotionally abusive in the past and has Borderline Personality Disorder and my girlfriend is very scared of her. Tonight she told her mom she would never talk about me again, and I decided enough was enough and left. I just really want to hear what unbiased people think I should do/should have done. I feel very conflicted and sad that I might have given up on someone I love very deeply.

Can you provide a brief overview of the text?
<bot>: I've broken up with someone who is emotionally abused by their parent for reasons involving her parent and don't know if I've made the right decision.
