feel played

Ok, so you have kids and you was in a long term relationship with a guy that's not your kids dad. So when you two breakup he start really showing his true colors on social media. Saying that he doesn't want anyone with kids, they are baggage, ect. Basically social media is his life. During our relationship he constantly ran social media to post about our relationship issues like our sex life & he never communicated with me when he had an issue with me. I always found out it was a issue because I looked on his fb account. So when he broke up with me he basically said "let's just fuck with each other so we don't gotta worry about the extra stuff and so I won't have to try to figure stuff out" I was so confused. He thinks I was cheating but don't have no proof of me doing so. He literally left me at that. I still don't know reason for the breakup up. I had to find out that he thought o was cheating from his Facebook account. I'm 24 very mature, love communicating & expressing myself. He's 22. I just really don't know how to cope with this. What would you do?
