Baby mama drama

I am 7 months pregnant with mine and my husband’s first child. My husband also had a child when he was in high school and the coparenting relationship is not good.

Long story short my stepchild has a homecoming event at school this week and I’ve been informed my stepchild doesn’t want me to participate in the ceremony, only his mom, dad and stepdad.

I dunno if I’m being overly emotional because I’m pregnant but I’m so hurt. I do was much as i can for this child despite being blocked at every turn and us only being allowed custody a few days a month for no good reason. But I’m so hurt and I don’t even want to go to the event anymore. If they don’t want me, then I won’t be there.
