I need advice..

I am 9 months pregnant and more than excited for my baby boy to be here any day now! The only problem is, my boyfriend and I are starting to realize that there are a lot of people we do not want around the baby, mostly his family. His mother has not asked about the baby once since we found out we were expecting, we sent her the heartbeat and ultrasounds and get no reply. We invited her to our gender reveal party and she refused to come. Now that I’m almost at my due date we thought she might ask us if my water has broken or anything, but nothing. His sister only talks to us if she needs something (a ride somewhere) and also has asked nothing about the baby. His brother’s girlfriend wished horrible things happened to our baby and his whole family defended her when I said I didn’t want her around my child. I don’t want them involved when the baby gets here and my therapist told me that that’s okay and it’s my child and I have the final word at the end of the day but how do I not feel so guilty about it? Any one else have an experience similar?
