My fiancé doesn’t want me to go to therapy

My fiancé has a big problem with me going to therapy. I really feel like I need to go to work on myself in so many different aspects- my relationship with him included. We have a lot of issues, but I don’t think couples therapy is best right now. I need counseling and he does too, but not together yet. We tried it in the past and it was a huuuuge fail.

I just want to be the best mom, fiancé, sister, daughter, friend, ME possible. I need professional help to do that.

I think he’s against it because the last therapist I saw, opened my eyes to him being borderline abusive and I left him for a while. She ended up leaving her practice and I haven’t seen a therapist since him and I got back together so I really need to get back to it because I’m seeing red flags in life again.

I don’t know how to get him on board? I just want him to be supportive of me trying to better myself
