what is the worst way to break up with someone?

Ghosting

Bring them to a big sporting event(in a stadium). And have the break up words projected onto the big monitor.

Inviting them on a romantic walk along the cliffs, then pushing them off.

For them to walk in on you while your doing the dirty deed with another in your bed

With Emoijis

Get down on one knee in front of all her family and give her a box that looks like a wedding ring but inside is a note that says "i hate you, i wish we never met. Now fuck off out of my life forever."

Then make a move on her mother
