Karen - I feel for you. Different set of circs but I had a split (relatively amicable but oh so painful for both of us) 25 years ago. It's not nice, it's hard, but you know you have done the right thing for you. Life is too short if things are not as they should be, and you need some space just for you. Don't rush into anything new - find out who the new You is, before you do that. You may be different when you come out the other end - I know I was.
Good luck, and we're here if you want to ramble a bit.
