FWB but more... RANT!😩

So I have a 'friends with benefits' thing going on... Except we both admit we're in love with each other. But we can't be in a relationship due to very complicated personal reasons. We have the best sex I've ever had, he makes sure I'm sexually satisfied before he even considers thinking about himself. He makes me cum three or four times before he lets me do anything to him!😂 We always spend at least a few hours together every day whether it's playing video games or watching movies and cuddling. He genuinely truly cares about me and loves me, he doesn't even have to say it. I can tell in the way he looks at me, talks to me and acts around me. Today he asked what would happen if he met another girl, and I nearly cried. I can't bare to even think about him with someone else!  I really want to be with him but we just can't be in a relationship together right now and probably not for a few years. What the crap can I do?! I don't want to lose him but I don't want to hold him back from other relationships, no matter how much it hurts me. I just want to cry, I really do!😓☹😭
