This is a bit long, sorry!
I have a FWB that I've known for a couple of months now, we met online and had a couple of dates but he decided that he couldn't see a full relationship developing but enjoyed spending time with me, talking to me and we seemed to be good at the sex 
I eventually agreed to see him as a fuck buddy. I've had them in the past but the others weren't so honest and I got feelings so this time around I figured that if I could keep the emotions out of it why not give it a shot. Getting to know him better, I don't think we'd work that well as a couple anyway. We're both out of relationships over the last 6 months but without clean breaks so things aren't too simple on that front.
My dilemma (if you can really call it that!) is this. I can't work out if he's being controlling or something else. I've been on dates since I've been seeing him which I've told him about. He wasn't thrilled but knows that I do want to meet someone for a relationship at some point.
He always asks if I've met anyone else yet and I'm honest and say no. When I ask him the same he says yes, I press him on it for info and he then says actually no, he's just winding me up. He's said that he wants me to be jealous because it shows that I care about him. He says I'm his girl and am the only one he sees. I just replied in a 'get over yourself' sort of way.
I do care about him, we have a laugh together, have a lot in common and I think he could be a good friend. I'm just a bit confused with the things he says sometimes. He doesn't back up his words really so I don't pay much attention and just carry on as normal. I know as soon as I meet someone I like I won't see him any more -ditto I guess for him too. But that feels a bit weird. I don't feel like I have feelings for him BTW, just that I'm used to having him in my life now. We don't go out anywhere together but it's not out of the question I think if I said I wanted to.
I've never had a proper FWB situation come to any sort of conclusion, with it ending or otherwise. Has anyone else? How did it end?
