Friends with Benifits with my ex HELP!!

So my ex and I dated a few years ago we broke up because of something so petty but throughout our relationship I felt like I was always pressuring him to commit to me.. fast forward to now and we recently started hooking up.. I know I know wtf? But the sex is 🔥🔥 and idk he just does it for me💦💦 so here’s the problem .. I still have feelings for him and every time we hook up I’m left feeling like I want more.. ive had fwb situations before but I always knew going into it that it’s strictly just sex.. at this point it’s been about 5 months of hooking up and I know this is all he wants.. so my question is should I keep seeing him for the time being and enjoy the good sex or should I lock him off? I’m really torn honestly I wish things weren’t this way☹️ and also should I just block him or should I let him know I’m not interested in fwb anymore?
