He said he will kill himself if I leave

I’m so unhappy. I have been with my boyfriend for 6 years and we have a 2 year old daughter together. Sometimes we are happy, but we have been through so much unhappiness.

He can be controlling, mentally/ emotionally abusive and I admit- I can be the same way when it comes to him. We are just so toxic together. We have tried therapy. My family and friends hate him. I’m constantly on edge and in a bad mood because we just can’t communicate. We are always fighting, but then make up very hard. He has been arrested and just the whole 9...

It’s so up and down and I’m exhausted. I have tried leaving, but he always convinces me otherwise. I know this will affect my daughter if I don’t. I just want to be happy but I’m so worried to hurt him. He has said if I leave he will hurt himself because there is no point in living....

I have so much lined up for my daughter and I- I just need to get out 😭

I would love some advice please.
