So, not only does he not foster any real DEEP attraction to you, he also wants you to keep your attraction to him most important. That's pretty selfish, isn't it?
You don't spend any more time on this. This is how he's going to be all the time. Decide once and for all if you can stand the negative energy and go with that decision.
If you decide to hang with him, you have to ignore his pissy comments or not back down when he start in. You have no guilt so you tell him to stop acting like a jerk every single time, then change the subject.
If you decide you DON'T need the negativity in your life (this gets my vote), then stop including him in your plans. Every time he brings it up, you mention your boyfriend is getting your attention...wish him well, and walk away.
You can't change this guy friend, but you're completely in charge of how much he can harm you.
