I just broke up with my boyfriend...

I would personally wait with relationships after just having broken up.

Just chill out. Hold back from a relationship right now and spend lots of time with 프렌즈 and family. Do sports, read a book, paint.... Do things to keep 당신 occupied and not thinking about boys. If your 프렌즈 start to talk about boys, walk away 또는 change the subject. 당신 need to get over your ex and then maybe, when you're ready, go for that other boy 당신 have a crush on! Good luck!
