Opt, I agree with Tal. I think you need to get to the bottom of what's really going on here. It's YOUR RIGHT. If he won't freely tell you about the $$ sitchuation, then I think you should by all means hire a GOOD PI.
He doesn't have to know about it. If there's not much more going on than what you already know, well at least you'll know. If there's more, then you NEED to know.
If he's keeping secrets, he's got himself in a big ole web spun by HIMSELF, and he's gotta be sweatin' it.
I hate to say it Opt, but the whole thing REEKS of deciebt. I hope I'm wrong, but after being lied to for over 5 yrs you learn to sniff it out.
Take care of YOU and your D. It's obvoius he's not going to. Leaving you like this is one thing, but to do it to your D is just plain wrong.
Who knows, once maybe when everything is out in the open (if there is anything)he'll be relieved enough to stop the madness. It's a shot in the dark, but stranger things have happened on here.
Opt, you'll be fine. You have an inner strength to be admired. Your D is so lucky to have you as her Mum.
Just do what your gut tells you to do. We aren't going anyplace-we're right beside you! Rachael
