Me again. Mr Teacher is still being a bit funny with me, or at least definitely not as he was before. We used to message loads, speak on the phone, we got on brilliantly, like lots of the same stuff, same sense of humour etc... We went from a few dates to spending nights together, at his house and mine, when our kids were with our ex spouses. Sex was (is) incredible, and we did other stuff like cooking and watching tv together, went for a day out etc. He was thoughtful and attentive, and I reciprocated that because I really enjoy being with him. I never went on OLD with the intention of finding a new relationship, but with him I felt like I'd found a soulmate or something, and he told me he felt the same.
However, as I say things have been different over this past week or so. There are far fewer messages, and the tone of them is different, although I can't quite put my finger on how. It kind of feels like either a) he did the attentive stuff to get the sex, and now he is having the sex he doesn't feel like he has to work at it, or b) he does have feelings for me and doesn't know what to do and is kind of pulling back. I can't work out which it is. Honestly, he doesn't seem like the sort of person who would do scenario a. He is definitely not using PoF (where we met), and isn't the sort of man who you'd expect to play games or anything, but at the same time I'm not confident it is scenario b either.
I don't know what to do. I am supposed to be going over to his tomorrow afternoon to stay for the night, but if all he wants is sex with no relationship, then I'm not interested. I don't feel that with him I could turn my feelings off, and I'd rather end it now than keep going in the hope that his feelings could develop. But at the same time, if he has pulled back because he does have feelings for me I don't want to say the wrong thing.
So, I'm not sure whether I should just ask him what is going on, and if so whether I should say it by message or in person, and how I should do it without saying the wrong thing. Any advice?
