I am still young, but that probably makes it worse if it causes me to be more emotional.. Do you have any suggestions on what I could do to help myself forget or recover?

What sucks the most is that he's perfectly fine and doesn't care at all

Great responses, thank you everyone. I can definitely see things more clearly now.

I blocked his phone number. I just don't know why he would have a reason to say all these things

Do you think he did it because he's just butthurt and wanted revenge or do you think he really meant the things he said to me? That's what I'm the most confused about
