and I don't know what to do.
I had told myself before we started this that if I started falling for him I would cut things off, because it was never the agreement to be more than FWB, but I don't think I can actually do that, because that would mean not seeing him anymore.
Likewise telling him that I'm falling for him, because I don't think he wants a relationship at all, so if I said anything, that would effectively be ending things as well
the only solution i can see is to just carry on until I get hurt, while hoping that it will turn into something. which isn't really very likely is it?
