Sooo he is a simp?

No. A Simp is totally different.

He is a self loathing, depressed man with a broken heart, driven to the edge of madness and willing to use the cruelty that this woman gives him to forget his true love.

He's not a real masochist, he doesn't get pleasure from pain, but pain helps him forget his 1st love.

It's like people drinking vodka to stop a hangover.
