Dont I'm sorry, I might be a bit jaded at the moment, but the name change/photo change would really put me off. I'd assume they were still fully active on the site. I could offer more palatable explanations, but the bottom line is, it's a dating site. There's only one reason he's on there, still on there and trying to make himself look more attractive on there.
When I was really interested in someone, I was worried about them seeing me online at all. If I'd changed my picture and name, I'd have expected some very serious questioning and for them to dump me, if I'm honest with you.
If I had any sort of emotional attachment to someone at all, I'd worry that they'd think I wasn't interested; was still active on the site; was seeing several other people and still looking...
I would be reining in those feelings and progressing with extreme caution, if I were you. And as for telling him you won't have sex if he's still looking and him really wanting to have sex with you... I'd be worried that he'll say/do whatever it is he feels he has to in the short term.
I admit that I am very cynical and I, sadly, do have a fairly low opinion of men in general. But I'm also yet to be proved wrong 
Hissy It's such a shame when that happens
I had it a couple of times. It's a real pity. I suppose it's those times when you realise just how unpredictable 'attraction' is.
As for me, well I think you're all right. Everything seems to have changed so dramatically in the last few weeks. But I suppose we got to that point where 'perfect' was dropped and we started to let each other see our real selves.
I just don't understand his motivation. Why invite me over and practically ignore me? Why ask to see me again when you've invited me over and practically ignored me?
I don't know what to say in the email though. I don't want to give him reasons because I don't want him to get defensive and launch a 'counter attack'. And I don't want it to turn into a conversation.
I think I'll just say, "Hi, This isn't working for me anymore and it's making me unhappy. It's over. FG" Do you think that's ok?
