I don’t know what to do

So my mom won’t let me see bf and I’m 21 I know crazy I’m an adult but tomorrow I plan on going to see him and stay the night with him I haven’t seen him in months and I plan on having my best friend cover for me but last time she didn’t and my mom went crazy and idk what to do bc I really love my bf and he keeps telling me that my mom is in the way of our relationship and I know this is going to sound crazy but he is purposely trying to get me pregnant so I will have a reason to see him but anyways she is going to ruin our relationship and he can’t take it anymore. I don’t know what to do
