I'm in college and I dated a girl in my same social circle. We broke up during the summer break and now that school is in session again, she made the first move to try and talk to me.

Nothing but friend-like texts. I was completely honest in telling her that I wasn't completely over her and I hate what she did (she hopped to another dude who in turn broke her heart). She then started to try and make me do things for her. I adamantly refused and then this morning when she asked me for something again, I told her to suck my dick.

It felt so empowering. She didn't take too kindly to it but I DGAF, haha

Also, how should I act around my ex since we are in the same social circle. I would much rather never see her again but I know it's not going to happen.

You did the right thing bro.

Just act cool and casual whenever you see her next. It's no big deal. The best revenge is to act like she didn't matter to you in the slightest bit.
