Should I stay or should I go? (sorry it's long)

I have been married for five years to a pretty successful businessman. I left two months ago because he had really bad, scary, screaming anger rages. My daughter left too, back in November, because of the stress in the household. (she was home sick, too). For these two months he had a settlement all laid out, ($800.00 a month for 6 months), continually asked if I was looking for a job, knows I’m on foodstamps. ( I have been a housewife). When I left, he immediately cancelled my cell phone and emptied my bank account. I got another cell phone and he couldn’t close my bank account because they wouldn’t let him but he did drain it. A close family member loaned me the money to engage a high profile solicitor and I had my husband served with divorce papers. He immediately started begging me to come back, has been calling me, begging to see me, leaving roses on my car etc. He has said he will go to anger management. He has made from 130,000 to $400,000 during the five years we were married. We lived a comfortable life but I certainly wasn’t shopping everyday and didn’t spend alot of money. He tells me he is broke and has nothing but the house, which is underwater he says, and a couple thousand dollars worth of stock. (he is vice-president at a publicly traded company). He says now I can bring my teen-age children over, both of them, which he previously didn’t want. If I divorce him I am going back to where my children are. I am so confused, I’m feeling crazy. Why did he not say all this before he was served? (my family thinks he is hiding something) I don’t know what to do any thoughts?
