I wanna go back home

So two weeks ago I left my bf because I had suspicions of him cheating I made my mom come get me and she had to drive 2 hours to pick me up.. I’m now at my grandmothers house and I’m so miserable I have no privacy.. I listen to my family argue you all day I just miss my apartment the quietness and just being in my own shit... I told everyone I wasn’t going back and that I came back to start a better life for myself and my son and that I was going back to school. My bf and I have an 11 month old son together so when I FaceTime him and see my apartment in the back ground I get so sad. Idk what to do but I don’t wanna stay here 😩
