I hate my sisters bf

We’re all in college. Me and “dean” were friends first semester and she said she hated him. Fast forward to spring semester they started talking. In Valentine’s Day they made it official after only talking for a week. It was like her personality flipped a switch. She used to be very independent and asexual. Now she’s acting dumb and is a completely different person. Here’s where my blood started to boil. Me and my sister share a dorm and one night he fell asleep in here. I was like okay and went to sleep. Apparently I’m a very deep sleeper because she lost her virginity to him ten feet away from me!! Now I don’t care if she has sex but at least respectful enough to not do it when I’m in the same room. When I lost my virginity to my bf she scolded me and told me it was disrespectful that I did it on my room at my parents house and told my aunt and grandfather but she can have sex right next to me ?! Also she’s not on birth control and they DONT USE CONDOMS. My sister is usually a very smart girl but the way she is now smh. They have been going at it like rabbits and even had sex when five other people were in the room including my friend who is mortified.

Anyways, the reason I hate dean is because he’s an asshole. He’s always saying shit to me like “ you’re fat” (I weigh 136 btw and I’m 5’4) and you look like a “12 year old gay pedophile” because I cut my hair to my shoulders. Also whenever he comes into the dorm he puts all his stuff in my side and refuses to move it. I came to the room the other day about to eat lunch and he’s sitting in my seat and refuses to move. Like excuse me?! How are you going to sit in my chair and tell me no?!

Last night was when I decided I officially hate him. I told my sister he could come over but had to be gone by 1 because I had early class. She said that was fine. 1:30 comes around and I ask him nicely to leave because I had to sleep and I don’t trust them to not have sex when I’m sleeping. He told me “no fuck You I’m not leaving”. I gave him 5 minutes until I asked again. Same response. So now I’m pissed off. I get up flip the light on and aggressively start cleaning (slamming drawers and throwing away his drink that he left on MY DESK). Well that made him leave but before he left he said “ I have to go before I beat her up”. Wtf?! And you know what my sister said. Nothing. She did nothing to defend me. She said “okay bye” in her little valley girl voice. How are you going to let your bf threaten your sister and not say a god damn thing.

She never stands up for me like i would for her.

So far since they’ve gotten together they have had two fights. Both times they swept it under the rug like nothing happened. Today was the second time. My sister comes in the dorm and a pissed off mood and goes directly to her bed. It’s been hours and she finally says that dean was being an asshole to her so she left him. She said “I’m not getting out this bed until tomorrow “. She said if you see dean tell him to come to the room. I said “why can’t you text him yourself ?” She said “I’m not talking to him”. I said why would I tell him to come here if you don’t want to Talk to him “. She said “bc”. I left to do some homework and texted her asking her to come read my paper before I submitted it. She said she’s not getting out of bed. I think that’s selfish of her because all week I listened to her practice her speech for her class but she couldn’t come down and read my paper once ? I get back and before I close the door I hear someone yelling down the hall. I didn’t think it was for me so I closed the door. Dean comes knocking a few minutes later and was like “I know you heard me call for you , you’re such a bitch”. My sister embraces him like they didn’t just fight so I call her out and say “weren’t you just mad at him?” Dean says “mind you’re own business “. I say “first of all she told me what happened so now it is my business and second of all if you don’t want me to know y’alls business then get out of the room because I’m not leaving”. He was in here for like ten minutes before he spoke to me again but I didn’t answer him because I didn’t want to talk to him. Once again he calls me a bitch and once again I have to stand up for Myself.

I literally hate him and hate who he turned my sister into.

Also he’s been engaged three times, had his ex name tattooed on his hand, and still wears his engagement ring.

Update: he just snap chatted me saying “I really don’t like you. No cap” so now he’s blocked on everything
