Almost 2 year relationship to fwb

Am

So he ended things off with me about 3 months before our 2 year but he wants to still be friends but we still do intimate things so fwb, the only thing is that I obviously get jealous cuz that’s my mans still (he’s not but he is) but he also gets jealous if I’m talking to a guy or if he thinks I’m fcking another guy. We got a hotel together and he ended up looking in my phone and looking at what guys I been texting or maybe how many and who but I took his phone and did the same when he took mine. But we got together again today and after we did the deed we were just talking a lil and blah blah blah well somehow it ended up with him saying how he can’t be emotionally available for me and it’s like it doesn’t make sense to me, can someone explain
