Ex bf of 6 years guilt trips me

I left my ex 4 months ago. I mourned the relationship about a year ago.. he cheated on me after our miscarriage, he flirted with women in front of me. I’d pay bills and dates. The last few months I had a conversation with him about me wanting to go back to school and I needed him to help me with providing. He had a whole tantrum about it. The last day of our relationship he was being sneaky, he had a way to prove things to me but he decided not to due to being petty.. I broke it off.

I had stayed with him this all those years because he has a son who I am so attached to and I didn’t want to upset him. Also because my ex had depressive episodes and I’d worry about him. It’s been 4 months and I’ve been going out with friends, dates, nothing serious because I’m not ready. He saw me out with a guy and my ex made a whole asss scene to the point where someone called PD and reported that I was being held hostage. EMBARRASSING 🥲

Point is he guilt trips me a lot and sometimes I do feel bad but I know it’s the manipultation… he had 6 years to get on the ball…

I have not blocked him on my contacts because he’s depressive and I want to know that he’s alive. I just needed to vent
