I shouldn't have said that

I told my grandmother I wanted to have a baby. I live with her and I've been through a lot. In my past I was sexually abused and now I just want to start my own life at this point. I explained this to her and she wants me to finish college first, which I agree with. My only issue is she brings it up all the time, she says stuff like"you don't want to cook dinner but you want to have a baby" she tries to find anything to say and add "but you want a baby" to the end. Idk what to do, she's not helping me deal with all my emotions and she's constantly bashing my boyfriend. (I posted in another group as well but maybe you guys could give me some advice)
