I feel so bad for my sister shes 19 and takes care of her low life boyfriend who does drugs and is an alcoholic partier. He is newly 21. She is 35 weeks and still working but barely has anything for her baby. She is crying to me because she doesn't get included in any partying or "fun" anymore and her boyfriend treats her like shit. Shes calling herself a fat pregnant bitch and says she wishes she wouldn't have gone through with this baby thing. How dare she say that about her baby.. Get over your drunken druggie lifestyle and boyfriend and take care of your baby. I feel bad for her kid. Im 17 and don't even have the childs father in my life and I don't cry around cause my baby is my life. If i lost her I would definitely go off the deep end. She is saying she doesn't want to breast feed because she wants to go out and make her boyfriend jealous. Omg🔫🔫 its time to put that old life away honey. Those days are long gone!!! Partying is NOT SHIT. Once maybe twice a month I can see but wow I'm really disappointed in her.
