I sent a video to a friend of mine that reminded them of their abusive ex, but I'm not going to apologize for it.
Why would you do such a thing? Do you think it was appropriate to send that video?
Yes. I know exactly what I'm doing.
Sending that video was the wrong thing to do. Intentionally reminding someone of past trauma is cruel and dangerous. You should apologize to your friend and not do something ilke that again.
They should learn to get over it.
People can't just choose to get over traumatic experiences, and you shouldn't make light of what they went through. Sending your friend that video brought up bad memories for them and was an insensitive thing to do. When you do something that upsets someone, you should apologize so you don't lose your friendship.
