Okay so, a little background:

I joined a new school this year, and I’d made a lot of good friendships with some of my classmates.

In the meanwhile, I had an on and off relationship with my ex.

We’ve been together for about 2 years and I broke it off bc of personal reasons.

Soooooo let’s get to the point lol :

I officially ended things between us about 3 months ago, and literally the day after - I go to school and look at one of my classmates, and I just thought to myself : “oh crap, he’s cute”

And now, about 3 months later, I’m stuck on this (absolutely attractive, cute, hot, and beautiful) boy, and he has a girlfriend.

What should I do about it? I Feel extremely lost.
