Should i be mad? Long

Samantha

So a couple of weeks ago my SO decided to let his best friend move in with us. Didn't ask me or care what i thought even though i barely know the guy and have severe social anxiety. That means now I'm super uncomfortable in my own house but that's not even what I'm mad about atm.

The guy had been making me mad a little at a time. He yells at my animal, he THREW my twelve week old kitten, and now one cat is missing. None of them ever got out before he was here and she's gotten out twice now. The first time she came back the next morning, this time it's been days and we live on a very busy road.

Last night was the last straw for me. My bf asked him to go pick up my sister from work for us because we had to go to bed early (keep in mind he's driving our cars and hasn't put any money into the house yet.) she gets off at ten. I wake up at eleven to the phone ringing because he didn't get her! He said he went and waited five minutes and didn't see her so he came home! This is ten at night, every thing in the plaza she works is closing. Instead of waking one of us up he just came home and got back on his fucking computer! What if she was mugged or raped? I'm so far beyond mad and my bf thinks i have no right to be. If i say anything about it he goes off and starts trying to make my sister out to be a bad guy. Idk how to deal with this but I'm about to lose it.
