My daughter is about to be 4 months old. The day she was born, her biological father was there and he did sign the birth certificate but we are not married. She also has his last name. At the time...we were still trying to work on being together but now...things are over between us. I realize that he is never going to change. He didn't have good credit before so he asked me to open up a credit card for some guitar place and he purchased a 700$ guitar. The payment is due this december and I know he isn't going to help me with it. And since the baby's been born...he hasn't even bought a single diaper or formula for her. When I ask him for money...which it won't even be able to go to the baby right now cuz of his stupid guitar...he keeps saying he doesn't have any. He is so stubborn and selfish. I really just don't want to deal with him anymore. I don't want him on child support. HE doesn't want to be on child support. He doesn't help me with our daughter. My mom is basically supporting her because I am currently not working and is still in school. I have little money saved up and it's all going to my baby...and now I'm struggling to find money for his guitar.. it's just not fair. I don't think he should have any rights over her and I would like to take his name off the birth certificate and change her last name to my maiden name. Is that possible without his consent?
The only time he's called me after I broke it off with him is to try and get back together with me. And twice he has stopped by unexpectedly to visit our daughter but for only 15 minutes or less. PLEASE help me change her last name. I don't want him to have any legal rights over her. He is not a fit father. He is too selfish. If anything were to happen to me...my mom should have guardian-ship over her not him. He is her biological father but he has done NOTHING for her. My mom had a piggy bank saved up in my room for her and last time he came...he asked to borrow 20$. I didn't have it so he asked to take it from there. I said ok but he BETTER put 20 back in there the next time he comes but now all I hear is...I have no money. I'm really sick of this. I'm such an idiot. Please help me any way that you can.
