What’s wrong with me.!!

So it’s been a year since my last serious relationship but I have been dating n I met this guy like a month or two ago n he was always trying to message me n if I blocked him he would text me from other accounts n we finally hung out n it went really good the second date we had sex n it was good too n we’ve only seen each other 4/5 times so far but idk I told him I wasn’t ready for a relationship in the future bc I have trust issues n he was like I won’t treat you wrong I’ll show you. He treated me good but out of nowhere the next day I had the urge to block him n I did n he messaged me on other social media but I blocked him too n a day went by n today I unblocked him n he already added more girls im actually kinda hurt I know I haven’t known him for long n I didn’t really feel anything at first but now I kinda have feelings for him n miss him 😭😭😭😭 idk what to do.! I’m sad

Update: I honestly didn’t think of it that way that I’m playing games. N I usually act this way now that I think of it maybe I’m the problem with every guy..
