tired of stressing for my Baby's father to come see him! he said he was coming today n then just now text I'm not coming. how selfish! his mother swears it's not his son but that was my bf at the time I was there almost all the time. I keep saying let's do DNA test but they aren't fr it. I hate my son has a deadbeat. he gets to text everyday sayn he wanna see him but doesn't come. idk what do now. he needs to help financially fr his son
