If "you don't want this", then it doesn't need to happen. He can't force himself on you in any way, including emotionally.
I'm sorry to be a worry wart (it's my nature), but I really want you to keep your wits about you now. It's very important. Remember his history. You are certainly vulnerable to the affections of another man right now. I'm afraid that he is taking advantage of this. In my mind, that makes him a threat to you. A true friend would wait for the right time - like...um..when you are single? or when you express an interest in others? etc.
OK, I'm worried about you. Don't allow any man access to your heart until you are ready to share again. From what I can tell, you have not really ended your relationship with your hubby yet.
One thing at a time. And, safety first always! I don't feel like it's safe now, when you are emotionally ....um..whacked

, to start a new relationship. Especially when it sounds like he is forcing it and you are avoiding it.
YOU are the important person here. Your happiness is all that is important.
em, the worry wart
