so there's more to the story then cathy; calling his office won't help you in any way i guess because as you've said the're filtering your calls. noone here really could tell you the right thing to do right now, it will be all up to you in the long run.

i hope things will be better for you and your kids, if your husband doesn't want to give you financial support then so be it, The One up there will take care of him :)
