So my SO'S friend "female" just came to the house to use our shower. Okay, that's fine.. Well then my SO went in our bedroom and shut the door (you have to go through our room to get to our shower). So I barged in there and they were just talking, on separate sides of the room, but I still got upset and started crying. My SO is now mad at me for getting upset.. I just don't know what to do anymore.
