IP I fully agree with Ciluzen, I think you need to drive the car now. I fully understand how scared you might be, but I guess for your own sake you have to do it. I was dreading to go for separation but I didn't have the choice as once my house sold there would have been nothing that I could have used as leverage. I was worried that it'd ruin my change of saving my M, it hasn't as nothing has changed.

What could be the worst case scenario? He has ready left you, him filing for divorce I'm not too sure as it costs a lot, even if he does you are already living separately so it's a kind of D isn't it?
Think about your kids and it affects them, and how it affects you. You are the most important person right now, and I'd not be so harsh if I didn't consider you as a friend. Please do what is right for you at the present moment.

Thinking of you (((((((hugs))))))))
