Emotionally abusive relationship

Has anyone had experience with an emotionally abusive partner before? I googled signs of emotional abuse and my boyfriends behavior can check like 5 or 6 off the list of abusive behaviors... he's never hit me or tried to control me or anything obvious like that, but its stuff like he brings up the past to justify his behavior, when he does something that upsets me I can't tell him because he makes it seem like it's my fault, gaslighting, stuff like that. He can't take the blame for anything, and there's lots of shit he needs to take the blame for.

He's mentally ill and therapy and medication has helped SOOOO much so far, and he is still working on his issues which is why I'm so hesitant to leave him. I love him to death but know I don't deserve it... but my heart keeps telling me that things will continue to improve. He's bad at processing complex emotions and I think therapy is helping. Lots of two steps forward one step backs happening.

I'm so exhausted and heartbroken when he does his stupid things but when I think about the full picture there has been so much improvement.

He made an appointment with his therapist for me to come in with him in two weeks so at least he's trying right? ☹️😅

I've talked to my therapist about it but she hasn't told me what to do and I just need a push in the right direction 😭😭
