Some situations need a hero. Unlike some others on this thread I don't take responsibility for my marriage failing, my ex beat me over things like the electric bill being too high and stepping on the brakes too many times while I was driving. One time I got beat for not emptying the garbage. I prayed everyday to Jehovah to help me love him and be a better wife. We were both pioneering and he was a MS.
ANYWAY even though I know now, he has some issues with anxiety, depression and most likely a mild form of autism I have gotten past the anger I felt for him. I treat our relationship like a business relationship because we have a son together. I never speak ill of my ex and I try to work with him in how he treats our son.
There is no winning as some have already said in placing blame. Someone has to take the high road. I live my life towards the end of helping my son get what he needs and if that means I have to bite the bullet and have a peaceful co-parenting relationship, then so be it.
