My boyfriends mom is being ignorant as all hell. I told her I didn't want her to be apart of my babies life do to many different reasons, but her husband (David's stepdad) was aloud to be there 100% for my baby. We'll today David had to go thru his mom to get ahold of his stepdad to see if he could take us somewhere and id give him has money. We'll she said her and Harry (stepdad) won't be do anything or David and I as long as she isn't aloud to be apart of the baby's life. I feel I shouldn't have to explain to anyone why I don't want them to be apart of my child's life. And if I did explain to her why then he would be butthurt and an even more of an ass to us then she already is. #IDontKnowWhatToDoAnymore
