Guy's Behavior

Am I overthinking this?

My baby daddy and I haven't been together in 7 years. He told me recently that he still cares about me and loves. That he wants to get back together. I told him I'm not ready for a relationship. I haven't been in a relationship since him. And that wasn't a good relationship. We had a good moments. And he's sober now. We get along and everything. But part of me feels like he's playing me. Because everytime he posts a picture of himself on fb at least the same 3 girls likes or hearts and might comment on it. One girl he said message him and asked if he was single he said not really cause he was trying to work things out with his baby momma. Then she said oh ok that she was curious about the female commenting on his posts even though his profile says single. Then she told him hope it works out for ya guys. But yet she still ❤s his posts and comments. Am I trippin or is that disrespectful? I don't know everytime he posts new pics I see more girls liking it. I'm like wtf? I can't say anything cause were not together. Personally I would care. I just dont want to be played in the process too. Dont make a fool out of me. Making believe that you really want to be with me but yet girls are hearting your posts. Am I tripping? What should I do?

Am I overthinking this?
