First off, if you, "feel like I make the wrong move it's over", then it's HIS problem, not yours! That wouldn't be the kind of relationship you would want to have, always walking on eggshells! I'm no dating expert but girl, you've got a lot going for you so just be yourself.
I was married for 18 years, divorced about 4 years, and just remarried in December. The best book I EVER read concerning men is called "Why Men Love Bitches". I would recommend it to every woman whether she is married or not.
I think I'd wait to reply to Tony again, but you need to do what is in your heart.
