The question should be....what's the cure for a child feeling rejected. The reason isn't as important.
The answer should be distraction. If the child is upset, then balance the upset out with fun and happiness.
When my son needs distracting, I take him camping in a tent and pretend to be less clever and get him to show me how to put up a tent, he decides where the beds go and the layout inside. I find that him doing the arranging makes him feel more important and clever, which is a good tool to counter balance him remembering the negative thoughts.
Reading stories by candle light in a tent comes with it's unique challenges.
Given that the weather is a bit cold out, the next better place to pitch a tent is the living room or the bedroom (if that's possible).
I tell my son that sometimes we can't do what others do, but we can do other things that we enjoy and can remember. The important thing is to remember the things that we did do and we did enjoy because those memories are the stories we tell to make each other laugh or smile.
I personally can't see any good in watching porn. If someone came to me and watched porn all day, I would not be feeling to happy about that, better they leave and watch it somewhere where I can't see it and be reminded that it's not for me.
By the sounds of it, the bloke wants you to ask him to join him, just to put you down.
Money doesn't buy happiness. It can make allot of unhappiness.
