Take a shit on her bed and say 'my body, my rules.'

I'm surprised more people aren't criticizing OP for wanting to stay in and eat chocolate all depressed after being dumped for a week. Normally I see those kinds of responses, followed by "get over it and go out and meet someone." O.o Still, OP, that's very inconsiderate of your roommate. Maybe you should get a loud vibrator or something and crank it up when she's trying to sleep. Or crank up a porno.

Roommates can be jerks sometimes :/

Awe sorry! You should tell her to be more considerate

my body my rules? that means if I want to have sex dobt judge me. What it does not mean is I m allowed to have loud sex and be rude to my roomate about it. I wpuld have said something along the lines of " you dont singularly own the place, we share, I dont want to hear you doing the nasty, that has nothing to do with your body, it has to do with the face that its bothing other people"

"My body, my rules" has absolutely nothing to do with having loud sex just to throw it in your face. Your roommate needs to learn how to treat other people. I hope you had somewhere to go, like your parents house so you can eat chocolate and cry in peace. My heart goes out to you.

Why should she have to be quiet and comfort you all the time? Go see your friends, let her be. She shouldn't be the victim of your problems.

Then leave for the day, go to the movies or something! There are solutions to your dilemma.

Play music from children's shows really loud. Troll them until you feel better.

Unless she's banging your ex, what does her having sex have to do with you? Stop trying to use your problems to cockblock your roommate. That's some "if I can't be happy, no one can" crap.
