Well, I'm not sure I'm that qualified to advise as I'm struggling atm myself.
We were together 20 years and would have been married 14 this spring. We always had our ups and downs but things just got progressively worse until his behaviour was affecting our DD as well as me and we were both constantly walking on eggshells.
He was devastated when we left...for all of about 3 months when he started internet dating. He informed us about his new GF at Christmas and our relationship, which was quite amicable, has been rapidly deteriorating ever since.
I'm not remotely jealous that he has someone else. I haven't regretted my decision for a moment. But he's currently living in our family home, cracking on with his life and not even paying maintenance whilst DD and I are stuck in limbo living with family with precious little space or privacy, and I've almost doubled my working hours to ensure I can support us I the future.
Can't help but question our entire marriage given how fast he's moved on, which makes me hurt and angry. He seems to have gone from respectful and considerate to thoughtless and unbearably smug - I almost feels likes he thinks this is payback for my finally having the temerity to leave him.
Anyway after all that waffle all I can suggest in the way of advice is this. Divorce is a kind of bereavement - even if you don't grieve for the person you will grieve for who you thought they were and the life you expected to have. And when you have kids you grieve for them too. It makes you question everything you thought you knew about yourself and your relationship, and sometimes about your other friends and family members too.
I think it's important to realise it's a process and there are stages you just have to get through. Enjoy the positive ones and take the opportunity to nurture friendships and build your strength for when the hard times hit.
Be kind to yourself and try to remember that this will not last forever.
I saw this quote today which I think sums it up rather well:
"You're going to be happy," said Life, "but first I'm going to make you strong".
Or as my friend says Keep Buggering On

There's a divorce support thread in that section on here. I'll post a link in a mo.
