OIM- my W wanted to watch Fireproof w/ me- it was still pusuit...she was BSing me...
Fireproof would be for when there is more committment from W...once that happens, books like 5LL and Love Dare will make more sense...you can brush up on 5LL and toy around w/ the diff LL to see what may get more results...affection and PT may be out, but the others may work if attempted in small doses.
Hang in there, I know its not easy...how's PMA and detaching?
