<human>: So I just found out that a girl I broke up with 6 months ago for lying to me, is 7 months pregnant. 

She didn't tell me out of personal spite, as she isn't a very good person.

But I found out, and she already has a name for the child and says that it is having her last name. 

So she's trying to say that she already has the childs first and middle name picked out and that the child will have her last name. 

I tried reasoning with her to make it a hyphon, as I'd be willing to compromise. And all she has to say is "no, my choice legally. Nothing you can do about it" 

Is this actually the case? Can she just choose to name it whatever she wants and leave me out of the equation? This is my firstborn son, and a mans first born son should have his last name. 

There's no way she can do this right? I have to have some sort of legal options or something. 

Can you guys help me out with this? 

I was excited to be having a kid, but this almost ruins it for me. I just feel like a sperm donor and a walking bank if this is the case. I can't believe that a woman could have all of these rights when it takes two to produce a child. This kid is literally 50% me, she shouldn't be able to make 100% of the decisions. 

If that's the case, then I almost don't want to live on this planet anymore. Let alone have a child, only for him to get fucked over by a female and the legal system in his future.

Can you give me a shortened version of the text?
<bot>: Got girl pregnant, girl is having first born son. Saying I get no say in the name, and that it will have her last name. Is there anything I can do here?
