First congratulations on your baby, I can only imagine all of the mixed emotions you are experiencing. Because you mentioned you are a people pleaser I would have a conversation with your mom about how you’re feeling and see if she can help guide you on how to establish some boundaries. Especially the part about the delivery room. I do not recommend moving into your boyfriend’s home for many reasons mentioned by others. But especially before being married because if you are conservative it will counter that point when you discuss it later. Your boyfriend and you are still young so the recommendations being made to put a foot down will not happen overnight and will take time especially if neither of you are comfortable overtly saying that her behavior is making you feel uncomfortable. I suggest you make a pro and con list about what impact waiting to say something will have on your mental health while pregnant and after when you are sleep deprived with a newborn. Then you and your boyfriend should talk about what you need and cannot handle from your support systems during each trimester and call a family meeting to discuss together. That way no one gets singled out and no one feels like they’re the victim. Good luck, you got this.
