Here’s what I think you should do. Look at the evidence, and accept the guy is not really someone you can trust. So he’s not really someone you should bother dating.
Someone was obviously into him enough to give him love bites, but he didn’t acknowledge them. That’s rude.
He asked you for a hug, then moved in for kissing. Why didn’t he just ask you if you mind if he kisses you, instead of ‘tricking’ you into getting close?
And here you are now, feeling confused. So he obviously hasn’t made you feel like you’re really special and he only has eyes for you.
I think the next thing you should do is keep your distance from him, and look for / wait for a nicer guy to get involved with. I suspect the current guy will be making moves on as many girls as he can. Don’t get caught up playing his games. Just walk away from him and get on with your life!
