Maybe he was chatting with the OW on his long wealks, and now he doesn't want to?
You can't put anymore stock in alien writings than you can in alien words, but if I had to guess, I'd think the last half is more about what would be needed to improve the R with YOU So take whatever clues you can from that - start showing him your interest in satisfying him sexually (is that what the reciprocity thing is all about? Does he always have to do all the "work"? BTW - I liked your approach to him last night ). Get back to your workouts. Send HIM a flirtatious e-mail when he doesn't write. Come home every day with a smile on your face like you are having a GREAT day. And quit making ASSumptions.
