What should I do?

Hey guys so I need some help. I recently told this boy I liked him and I felt pretty confident about it.

Lately I’ve noticed this guys I know. He used to have a crush on me and I used to like him as well. We have been exchanging glances throughout the day and I think I’m noticing some feelings for him again.

However I just told this other boy I like him and I don’t know what to do.

Please help me!
