I'm in desperate need of help! (Long)

I'm 20 and just had my first about 7 weeks ago. Her father didn't really know I was pregnant because he had moved out of state. I told him and sent pictures and he wanted to step up. But after a day he stopped texting talking to me at all. I then assumed ok whatever I'll get him on child support or just ask him to sign his rights away. So I met up with a lawyer and got everything I needed for him to sign away custody and then I texted him telling him giving him a heads up on what I was going to do and if he was sure this is what he wanted and this was the conversation I'm not sure what to do. I'm scared.
