OP: I was in a FWB situation for arounf 7 or 8 months with a guy. We only left the house once, the rest of the time was just the two of us and was secret to most people in my life (my reasons, I had only left a LTR before). We didn't speak to each other except for when we wanted to meet. It startred to get a little bit more, both of us (I know now it was also him, but I thought it was just me) neither of us wanted to be in a "relationship" as such, he freaked out and it ended. I liked him a lot, and the sex was amazing.
I had 6 months where I saw a few other people, had a lot of fun, then we started seeing each other again. For about 3 or 4 months it was very much just sex. Then something changed in him and me I think.
Basically he freaked out before because I had just left a 21 year relationship and he coulnd't work out why I didn't want to be out seeing as many guys as possible. I freaked out because he is lknown for being a bit of a commitment phobe and I didn't want to get hooked so I held back.
Fast forward 2 months of so, we are very close, he is very keen, we have a lovely thing. It is almost close to being public and me tell my ex. Hes been patient, kind and we still have a lot of fun. I am still holding back, as is he, but really we are just seieng where it goes. I know it probably has an expiry date, but while its good, it suits us both. Tell him, if he says its not reciprocated, then move on. Dont keep having sex with him, it will lead you to heart ache.
