Advice needed!!!

Long story short my husband and I have been living separate for 5 months. I moved out because he wasn’t helping with our daughter, snapping at me constantly, lying, and just being disrespectful. He has mental health issues he hasn’t dealt with, thinks counseling is stupid, and won’t take medication for depression. He’s lied about taking medication as well previously. A year before I found him engaging in a sexual conversation online involving fantasy roleplay and he denied it then later confessed after I asked again so that hurt my trust a lot.

He said he would make changes like stop using marijuana multiple times a day and making changes to better his health and work on his anger and take medication.

None of these things have happened but he’s saying we need to move back in if we want to work it out. I don’t feel ready or comfortable but I don’t want a divorce either. What do I do?? What would you do?
