Ladies, I need some advice.

I need to know if I’m over reacting.

Ever since I moved in with my fiancé to my mother in laws she’s has given us zero privacy boundaries and she’s always had some rude comments to tell me during my pregnancy. She’s old school Mexican and believes a lot in superstitions. After having my baby she basically wanted to raise him the way she raised her children. I breastfeed my baby and afterwards I pump. She hates the fact that I pump and freeze the milk. She threw away the first 6 ounces that froze. My baby is currently 4 months old. During his first two months she would come in to the room without knocking on the door when he was crying. She would stand and watch me with my baby for a while and sometimes she would reach over to try to take him away from me. I always told her that I didn’t need her help. I never let her hold my baby at night Bc every night she would get super drunk! I know all she wanted to help but that was a big no. I talked to her about it but her response is if she raised her children and her first grand baby while being drunk she could carry my baby.

The first week of postpartum I felt extremely overwhelmed and left to my moms house and stayed there for a week. When I came back she had came in to the room, moved stuff around to her way Bc she didn’t like how our room was and did our laundry. I thanked her for doing our laundry but i felt uncomfortable with the fact that she opening my drawers and re arranged the whole room her way. Four months in and I noticed that she like to come into our room while we’re gone. She claims that it’s to take out the trash. I take out the trash every morning but I started to notice some of my stuff were being moved around like she was searching around. I got upset and told my fiancé, he thinks that I’m over reacting and he calls me ungrateful Bc we are living at my In laws while we save up money. Its 3 am at the moment I’m pumping and she just opens the door to my room and when I yell she says “it’s me, I thought y’all weren’t here” she saw me and my fiancé were home.

Am I over reacting for feeling this way? I love my mother in law and want to have a good relationship with her but lately I have been feeling anger towards her for not giving us privacy, making rude comments about my parenting skills, and wanting for me to follow every unwanted advice from her.

Every time I want to talk to her she’s drunk and when she isn’t I don’t have the courage.She had the same issues with her other daughter in law and she talks badly about her. I don’t want to start any drama with her.
