I don't want to keep my daughter from her dad but he disrespected me , and on top of it went behind my back and took my daughter around someone i don't know like my daughter could of been harmed ......

But why will i let him treat me like that i don't want my daughter getting treated like he's doing to me

Im i a bad person to block all contact with him and delete his number .....like he barley even helps and she's a month old
