I am extrodinarly new to this and really wouldn't do this if not so desperate. But i really need some advice from anyone. I am 17 years old and had been in a 2 year relationship with the girl who is now going to have my child. She is towards the end of her first trimester and she conceived entirely not planned, we had been very rocky and broken up for several months when it happened. About a month after she said she was fed up with me and my "anger issues" and now does not want me attending any of the appointments being part of her life or the childs life and doesn't even want me to sign the birth certificate. I want to be part of my childs life and the process before it's life and would be more than willing to take custody of this child. Does anyone know if theres anything i can do legally?

Welcome to the forum.
Here's the deal....since you weren't married you pretty much have no rights at this point in time. She can make all the decisions and if she doesn't wish to include you in any of it, she legally doesn't have to.
Your rights to be a part of the child's life can only begin after the baby is born. You can file for a paternity test to prove you are the father afterwards and ask for visitation or custody, and you will also be responsible for paying child support. To get custody would not be easy, you would need to prove her an unfit mother. You don't say anything about her being unfit, just that she chooses not to have you involved right now. You do mention her reason is for your anger issues so I get the feeling that she would definitely be fighting against giving you custody, but unless she could prove you a danger to the child....you would at least be granted visitation, so it's not like she can keep you out of the child's life permanently without good cause. Again, without her agreeing to have you involved right now, you can only wait it out for now.

The only other thing I can offer is IF you do have anger issues. I am not saying you do but IF you do and you want to have parental rights you could certainly go thourgh and anger managment course. If she has proof that you do have anger issues this would show the court you are serious about wanting to be in your childs lfe and are willing to do what ever it takes. I don't know the whole situation of course. Just a tought.
