Is it normal that i'm not heartbroken after a break up?

it is normal for you to feel this way. Yall were just meant to be friends, and everything happens for a reason, if yall were meant to be together, he would have made an effort, so obviously, you were meant to be with someone else. When you dump someone, you aren't supposed to feel bad or sad, you are supposed to feel relieved. so it's completely normal for you to not have a lot of emotions about it.
