does anyone else experience stuff like this??

My fiance has other girls over, lies to them that I just break in the house and won’t leave and he doesn’t want me here and tells girls he “tells me to stay in the bedroom cause he doesn’t even wanna see me” and then threatens me to not come out the bedroom or make myself known??

This just happened again tonight but one of these times he actually full on cheated on me in the living room while i was in the bedroom. and I don’t know why I can’t get myself to leave him
