ADVICE!!!

Before we get into this please know I am only 17 years old.

Yesterday my boyfriend and I told his parents that I’m pregnant. I had told them my sister had shown great interest in doing me a baby shower and gender reveal.

So today I get a text from his mom saying both of his sisters want to be involved in the gender reveal and the baby shower. Mind you his sisters have never said anything nice to me or about me, one has yet to apologize for stuff she ran her mouth about me that she had no business doing, gets mad at their brother for choosing me and defending me, etc. Overall, they treat me like shit. Therefore, I really don’t want them helping with my shower and gender reveal. I don’t think it’s fair to me.

I am the mother, the one carrying the baby , pushing it out, and a shower is more of a “motherly” thing which then leads to me believe more that my family should be able to do it. I have no relationship with his sisters, we don’t talk, and we just generally don’t get along. I’m not saying they can’t be there or involved in the baby’s life whatsoever.

So am I being petty? What would you do in this situation? How do I tell them I don’t feel it’s fair to have them be involved in the planning after the way they have treated me?
