Hey..

I don't want to put thoughts into your head, but is there any chance that he may be having an affair? I agree with Leed's thoughts here. If he was out of town and doesn't talk to you.. and doesn't talk to you at home. Also the lack of desire.
Do you think there have been any other signs to point towards this? I really don't want to upset you, but thought it may be worth considering as there surely has to be something that is causing his behaviour towards you.

Hugs
