<human>: So, my daughter who just turned 6 months old is the love of my life. I've been raising her on my own since she was born. Because her father, who I really dont think deserves that title, hint the "sperm donor"... has been in and out. He has never been consistent in her life. She lives with me full time, and always has. He doesn't pay child support, he doesn't pay for anything.

I haven't heard from him in over a week. I tried being the bigger person and asked him if he wanted to go to her 6 month check up, and no reply. After I got out of the doctors, i sent a message asking if he wanted to see how it went, and I then realized he blocked me. I always try to be nice to him and set aside our relationship because we're parents. But, it seems he never wanted to do that. I have sole custody of her already.. But should I file for child support? I can barely make it by anymore. Should I file for full custody? I didn't want it to end up like this, but I really don't want her growing up knowing who he is, and then him just constantly leaving. That's not good for her, and I'm just trying to do whats best for her. Please help.

Can you give me the gist of the text in a nutshell?
<bot>: Father of my child went MIA, blocked me on everything, should I file for child support and/or full custody?
