Back-scratching?

I consider myself as a good back-scratcher.
Whatever the other half requests me, it is always hard for me to turn it down.
I would love to scratch your back, however, you should scratch me in return!!
This man cleverly manipulated my mind and knew that I was expecting that, and maybe I'm still am!

Mais.... jamais. Jamais. Jamais.

His message to me was the last and worse msg that I think I would ever get.

I got myself into this worst ping-pong I've ever played,
It won't b really that good cuz one can't always run for both ends.

La gon,
waan jai.

I just wish I don't have to see you again.

(Give me a summer, then I'll be fine. )
