This is a tough one.. I sympathize with you, I too am divorced after being married to him for 10+ yrs, and I have 4 children with him. I'd suggest counseling to get you thru it. I'd say you should stay until your daughter is out of the house. Then she'll see how you are making a sacrifice for her & it won't be forgotten. Also, you can get over him, and actually wish him well with his new marriage. It takes a lot of strength, but to be calm and show that you can do it shows character and the ability to move past him. Get involved with some other moms or singles groups. Go have some fun! Your daughter will thank you for it.
