I cant and wont rebuild this marriage by myself as I am not the only one that brought us to where we are today. My son however deserve a mother and a father. So pull yourself together!
What do i do? If i focus on myself, she says i'm not trying. If i focus on her, everyone says i'm not DBing. I can't give up!
Not sure if this is the best response, but my effort anyway:
"I agree that this marriage takes both of our complete energy and focus in order to be successful. I am taking some time to evaluate my ability and desire to provide that. Regardless of the outcome of our relationship, our son will always have his father in his life."
