Why can't he make up his mind?

In my opinion, he is behaving like a typical MAN. No offense to any MEN. Men are afraid of commitment. They don't want to lose their autonomy. If you want something more from a relationship, then this may not be the one for you.

BUT if you are ok with this and you don't want more from him, then cool. Continue to hang out with him but date other people as well. Don't wait for anybody to see what a gem you are, his loss if he misses the gravy boat.

Good luck.

Either way, I think you should say something like ".listen, I don't want to be your girlfriend, so you can stop freaking out about how we hang out." OR "listen, I want more from a relationship and it doesn't seem that you want the same, so we should not hang out as often as we do because I need to focus on getting what I want."

See how that works.

This guys sounds like he's got some commitment issues. The reason he keeps coming back is because you keep letting him do so. If you want something more serious (such as exclusivity) say so. If this scares him off then he's not the one for you. How are you supposed to advance in a relationship with someone if they can never give you the chance to advance. Another possibility could be that he's waiting for you to pipe up and say that you'd like him to stay or go but not continue doing both because you won't stand for it. Yes it's only 7 months but I think it's about time you have the "What are we doing here" talk. Especially if he's over 30. It's about time he stop bouncing around like that.
