My husband is less than desirable in a lot of aspects. He flirts with other women, asks for and accepts nudes from them, pays for nudes, is constantly deleting apps and messages off his phone so if I go looking for stuff there's nothing to find (snapchat and messages I see pop up on his phone are the big two, and I can see it, I'm not crazy) then it's just gone. He's signed into that Ashley Madison sight for cheaters. He doesn't chip in on the bills (except of course the phone bill) I pay everything else. 3 months he didn't pay the car payment, I didn't know until I started getting calls about repossession,i had to drain my bank account to pay it off and catch us up (thank God we still have separate finances)

I'm looking to leave him, I just don't know how to do this alone, I'm terrified and emotional and exhausted. He's a great dad, we have one baby at home and another on the way. I would never take his kids from him, but that doesn't I should have to stay right?
