Can I vent?

I don’t have a lot of friends to vent to so I’m gonna try here to just get it out. With my first baby my mom was in the room and the baby’s father(I was young also) but since then my mom and I haven’t been getting along too well sometimes. I’m now pregnant again and due In July. I originally wanted the baby’s father in the room only him instead of my mom also. She asked me if she could be in the room I told her what my plan was and she got completely upset with me and I understand her being upset. I am older now and would just like to be me and the dad this time but she won’t listen to me and how I feel and want this time. I told her I might change my mind when the day comes but she’s not having that for an answer. She’s been trying to make me feel bad for my decision, she knows how easy I am to fall out of my decisions and do whatever it is to make anyone happy and that’s all she keeps bringing up is how “she’s going to get her way”. I’ve been upset about this for a few days now and can’t seem to get over it yet. 😔
