See Tom, Bethie is onto it. If she was the person you fell in love with in the first place this would be a simple choice. You would jump all over it.
She is not that person right now and may never be again.
Please do not confuse what I have posted to you as me telling you you should try. Not at all. All I care about is you and the talks we have had in the past about your son. No matter what your decision is, I want you to have a clear heart. I want you to feel like you did what was best for you, and your child.
I spoke to Ty earlier today and told him I would give you his number. He would love to talk to you. He went through a very similar thing here. Is he back with his Ex, no (of course she is a psycho hosebeast). He is however in a very loving relationship with a wonderful woman and he feels no remorse about his decisions.
