Seperation from fiance

Hi I am new to the forum. I've been in a relationship with my ex for 10 years it's been a rollercoaster. He loved bomb me form the beginning felt too good to be true. He is a people pleaser and very talkative to anyone. He had a very bad childhood I felt sorry for him

I realised that he was lying about stuff and twisting his words . I confronted him many times but he manipulated me that I believed I am sensitive and taking things wrong

His friend told me 2 years ago he has bipolar he denied it when I asked him. He did mention borderline but never said anything further about it. He was in hospital before we met trying to [self harm] [edited by moderator] . He is not on medication and not getting therapy. He did say he was going to hurt himself while we were together when we had problems . I felt disrespected a few weeks ago and told him about it. He denied it got defensive, shift the blame on me and played victim again. I clicked that this is a pattern and my feelings are valid .

I broke up with him but still feeling confused. I was in an abusive relationship before him and still wonder if I have a problem . 🙏
