i cant give any advice because i am going through the same thing myself the only thing i can tell you is whatever you do think of your child, what ever is best for him/her is whats right. Yes it does hurt believe me i know but the only thing that keeps me strong is my kids
you have to ask yourself is this what there life should be growing with mommy and daddy fighting all the time?do i want my life to be this way? or do i want to give my love to someone who can appreciate it and return it the same?? you have to stay strong for the kids and yourself it will pass the heartbrake you are better off without someone who doesnt love you then with them!!!
