You've known this man for a long time and, you've both been through counseling.
But, in the final analysis, ask yourself this...
Does a man who is capable of locking people in rooms; unplugging phone lines; cutting off electricity and denying the mother of his child naming rights for their baby have the emotional and psychological maturity and stability to provide a healthy and loving environment for anyone, let alone... a vulnerable child?
... let the answer to this question be your guide.
Wow, are you in a situation. I can see why after 12 yrs. in a relationship, you are not married. Your partners sounds potentially dangerous. A walking time bomb. He has not physically harmed you yet, but it's just a matter of time that he will, so good thing your not married.
Also, why are you not married by now...just curious? Your family has every reason to be concern about your well being, unborn child and safety. Although I think he is dangerous, he is the father of your child and his name should be on the birth certificate.
Your b/f and family simply don't like each other and don't have to like each other, but family is blood and it's bond that can never be broken, so he loses on this one. Although he has a right to his son, you have a right to your family and your son is part of that family, so once again, b/f loses. He simply does not have to be present at all, so he can just get over it and stop squabbling like an infant.
Name, if it is a boy and if you want your father name, so be it and work it out....b/f first name, father's middle name, but go ahead and honor your father with the gift of his name to your child.
Secondly, use caution in this volitile relationship...re-evaluate wether you want to spend the rest of your life with a man who can possilby kill you under anger. Good luck, Judy
