He doesn’t want to be with me because of my mom

My mom likes a guy for me but I don’t want him. She told me that it’s either him or no one. I’m 18. I told her it wasn’t her choice but since I’m living under her house, if it’s not him, I can’t bring anyone home. My bf got sad because he feels that he’s tearing us apart. I asked him “do you want to stop this then?” He stayed quiet and drove me home. Didn’t say a word. When i got out, all I said was “you’re letting them win” and left. He didn’t text me all last night nor this morning. I’m sad because I love him & I only want him, but my mom doesn’t approve of him, she only likes the other guy because he has money.
