Single mom

Am i the only mom that feels like i should've never told the father of my child i was pregnant and just to have my baby and go about my life? Is that wrong? my daughter is a year old and he hasn't done nothing for her and she doesn't know him the only time he came to see her she was 4 months old so that was a year ago. then Sunday he had the audacity to ask if i get taxes off my daughter like he deserves to get some money off her i just want him to stop bothering me.
