I feel trapped...

I have been with my current boyfriend for two years now, he moved in with us because of his mom kicking him out (just for her own pleasure) we had sex once and my mom caught us. I wasn't allowed in my living room (where he stayed), had to be fully dressed, obviously. We couldn't even give hugs in front of anyone in my house.

I graduated last year, have had a job since I was 16, as soon as I could I got one became manager and everything . We work at the same place, easy transportation. But now,we haven't had sex and trust was back. I was allowed in the same room again, just had to sleep on different beds.

We are currently working on our new house and trying to get out of my moms house.

But now, we tried to have sex again (always with protection!) and she came rushing down and she heard us scatter, didn't see anything just automatically assumed she knew we were. And now Its starting all over she sent me to my room and instead of talking to me she calls me disrespectful (which it was and I know.. 😕) says she's throwing him out and runs to my 16 year old sister and tells her what she's going to do with me and my boyfriend... I'm 18.. she talks about treating me like an adult but everything I do with my bf is disrespectful. Before all this couldnt even sit on the same couch!

I feel like o can't do anything... am I over reacting or I just don't even know what to do...
