Ex problems

This guy I was in a relationship with I ended it in October due to baby momma drama lack of communication low self esteem no motivation to do better and be better love to play victim spoiled as well poor hygiene was together for a year and out of that time I got tired of basically playing the role of his mom and not a girlfriend I have 3 kids of my own I shouldn’t have to keep telling a grown man to wash his asss or get a job or he should prioritize his money on things important and not so much weed and cigarettes. So a few weeks before we broke up I started back communicating with my bd so he could help me with our 5 year old who was cutting up in school badly having him involved really improved her behavior so I didn’t see where the problem was especially when my ex wasn’t much help when it came to her misbehaving he actually encouraged it . So when we broke up I didn’t disclosed it to anyone because it was nobody business but ours but instead he’s out her telling everyone I know I left him for my bd remind you my bd has a gf and I also left him because I was starting my career as a cop so I couldn’t have the bad or illegal behavior around me he had plenty of time to decide if he would change his ways or stay how they are and lose me . But people are constantly telling me and showing me stuff he’s saying about me on social media that I’m a hoe I’m not loyal don’t trust a b**** with kids or a bd nd a lot of other stuff but I haven’t been able to say anything to him because I’m too focused on finishing the police academy. I wanna say something to him or should I stay silent
