help atrl, you are all fabulous

How I've handled it, in order of effectiveness:

Nature walks/hiking
Clubbing & hooking up with someone new
Hobbies
Hanging out with friends
Setting new goals (i.e lose weight/bulk up, get a better job)

Basically, anything that will divert your attention from them, and help you to regain a sense of independence.

By streaming Heartbreak is a mother****er Funhouse.

Listening to music that relates to your issue. It always helps me to listen to Adele etc. People who've been thru it and express it in song and have grew from it

**** their dad

By listening to fourth studio album by Kanye West called 808s & Heartbreak.

The only thing that helps me is surrounding myself with new people and most importantly, TIME

don't hook up with anyone new!
Find a new friend. Honestly this works the best. Just a friend, no romantic interest, but a friend and don't nag them about your heartbreak.
Working out apparently works too idk

Go listen to the ultimate heartbreak album "Take Care", by Drake !

I never really had to deal with it, but if I had to, revenge! I have a special target for darts with the faces of the people I dislike on it.

I hate to be a pessimist but I never really found a way to deal with it. Eventually as time goes on the memories just fade into the back of your mind and you make new ones, hopefully with better people.
