Ok, here`s my take:

Your H is pulled. Torn between nis fantasy world, OW, maybe army culture, long stints from home on the one hand, New You, his adoring kids, his family values on the other.

His selling car, taking you off c card acc, and changing relationship status on facebook may just be olive branches to OW. She must know he`s spending more time with his family than before, she may even have seen pics of you, knows the kids he truly loves are so upset by all of this.Knows her position is precarious.

Your dbing your ass off and doing so well. What does she have that you don`t?

Maybe you mother him too much. Maybe he`s stopped(to some degree) seeing you in a sexual light(hence his silence as he tries to cope with the possibility of your having a BF) He may feel you`ll always be there so he can have the best of both worlds.

Yes, I think he`s drifting closer. Your D17 noticed and girls her age are tuned in to such things. Your kids have noticed the changes in you(you`re hot! as one of them said) he has too.So as you pull him towards you, perhaps OW is pulling on the other end.

All she can do is indulge his sexual fantasies. I think if you mother him less(no more free food) and indulge his need for eye candy more he may realise he`s on the wrong ship.
