Hang in there! Lots of tough love advice by some of the guys here but I have to admit that as a woman - they seem to be right that in this situation, showing your strong,happy,be-fine-without-you side is what makes sense! (However if you two do get back together - you'll need to work on learning how to listen to her and romance her - women want to feel sexy and romanced not just during dating but during the marriage too!)

Now what do you do when SHE contacts you? Picture in your mind how you would talk to a woman you barely know on the phone if you were having the best day of your life! You wouldn't have a lot of time to talk because you are getting ready to do something amazingly fun! Nothing negative she says would bother you in the least or cause a reaction. You'd only react to the positive things she says in the conversation with little jokes or even subtle flirting/double meanings (only if it flows natural - you wouldn't push it!) Your conversation would always look on the positive side of things.

I understand about not being interested in playing x-box so much lately - I feel the same way about my hobbies. But maybe if you try to force yourself to do it, you'll soon start to feel some of that enjoyment back from it?
