Just a simple question.

Okay so I was talking to this guy for a while he started being an ass so we quit talking as soon as we did he got a new gf then come to find out he broke up with her and randomly hit me up And we started talking again. Then I find out a few weeks later he posts on some girls fb saying "hey your cute 😉" and loved everything on her page I confronted him about it and he got very defensive and said he was doing that so her ex could see and he didnt really mean it? Am I the only one not buying his bullshit? Thoughts?
