Divorce

Idk what to do . long post ahead … My husband and i have been together since 2014. We got married in 2018. Well he cheated with a coworker and we seperated for 6 months and he wanted to do counseling and fix things and coming from divorced parents i wanted to try and fix it for my kids. i have love for this man , hate to see him hurt but idk if i want to stay. Its been 2 years since and nothings been the same. i love him but i dont feel “in love” … Hes been really mean towards our kids and i lately he has bipolar and depression but wasnt taking meds now that i brought up leaving he wants to start them and says hell change. im just tired of feeling unfulfilled and waiting for the change . im just heartbroken and im realt stuck. i just dont know if i want to continue this marraige
