Tea on my blanket

I just spilt my tea all over my blanket, and now I am a little sad because my tea is gone and everyone drank all the tea, so I have to make more tea... I am excited for break though!! I have my final exams of the Semester coming up, and I am just glad to get away from some of the people in my friend group. One of the people in the "group" is my ex, and he was really creepy and sexualized me a lot even though I told him I didn't like it. He was really physical toward me and would force himself onto me, and he was just gross to me. Being around him makes me uncomfortable, especially because it's like he copied the way I spoke or wrote since I have a certain way of spelling or saying things to make my writing more like me (In an informal way, so I kinda have my own slang that I made up for words, but it's just how I say things but written in my accent?) And he has a new girlfriend (It's been a couple years) but he still watches me and is weird. My friends know he was weird to me, and two out of the 5 people are still friends with him, whereas the other three are disgusted by him and hate him. I just don't get it, the girl that is still friends always talks about him and is always bringing him up around me. She KNOWS everything that happened? She knows how he would touch me inappropriately when I didn't want it and told him not to? I don't know why she is still friends with him and invites me to hang out with them. I don't even want to sit around them, but she follows me around, and he follows her. Sometimes it feels like he still likes me, and I wish I could rip my skin that he touched off. I can't stand them, and I want them to just leave me alone.
