MIL issues

I feel terrible I confronted my husband that I don't want his mother living with us and why do I feel guilty I was gonna stay quiet about this for the rest of my life and I couldn't I was just too bothered and yes we had an aruguement I did the me or her thing and of course he said it's over he's the type to do that and well I feel like wow I have to fight in my own relationship to have a right or to even have a say I'm currently pregnant and we where great no fights nothing should I just kept my mouth shut or was I just wrong for saying that?
