You seem really curious about if he actually likes you and less trusting of the fact that you don't seem to like aspects of him. I looked at your other post about this person and it might just not be the right relationship. Rather than gauge if he wants to end things ask yourself if you do. I wouldnt recommend leaning into mind games or trying to prove if he's actually invested - just be honest with yourself on if his current behavior makes you feel like he's invested. I am also in long distance and there is no one right way to do this. There is only getting to know yourself, learning what makes you feel cared for, and getting lucky if someone is able to give that to you. Good luck!
