i only have one thougnt on this all - even tho your h says he's perfectly happy to support you and kids, house, etc. (forever).
i would say view this with skepticism. he may feel it now- he may even mean it and do it.
i'm just saying - from my personal angle- my h is very generous- when it came to me saying okay- give me house- not so much.
there's a point maybe when they either feel like they would lose control- do lose control- or have no intention of carrying a burden of finances is there's "nothing in it for me". my words- maybe his sentiment.
i'm just saying- veiw his generousity as something maybe yes, maybe no. no one can tell where it will lead if you totally get forceful and push the situation-separation, whatever.
i am world's biggest chicken and "over-thinker" of everything.\ soooo- tht's my outlook- look out- for yourself. use diplomacy if possible and don't give him a chance to be all righteous and indignent and make you pay.
don't mean to rain on your parade- just the chicken's eye view here. xxoo have a grat day.
