My Baby's fathers dad is so rude to me I can't stand being here anymore. So yesterday was Brian's (my baby's father) graduation, well I put on my grey and black striped shirt that kinda shows more of a bump. and his dad was like "your belly is showing to much, go put something baggy on" so I went and got Brian's mom and she told him I looked good and to leave me alone about it. Then when we got outside to get in the car he was like whispering when I turned around that he didn't want people to see my belly. Then when we wer at the graduation thing sitting down he grabbed the program paper thing and put it on my belly like trying to hide my belly. He's just fucking rude. I dont know what to do anymore.
