Get away from this man! Get him out of your life totally! I have a lot of explanations for the way he is acting, and NONE of them are beneficial to you.
QUIT dealing with him USING the EXCUSE that he is your son's father. He is a sperm doner...nothing more.
You have to put you and your son in front of his needs, and you continue to not do that.
You can email me if you'd like...I would like to talk to you over the phone if you want. I'll give you my # if you email you.
Quit being a schmuck. You have a wonderful heart, and he is taking advantage of that....you need to let him go COMPLETELY. Send his letters back. Call the prison, and tell them that you do not want him to write to you. They will not allow any more letters from him to come to you.
Think about you and your sons ABOVE him for good. GET RID OF HIM IN EVERY WAY, SHAPE, AND FORM.
