^^I'm with Take2.
Exactly why you should immediately delete this sort of thing so you don't look even when you're tempted.
Don't respond. Don't let him know you looked. Next time, don't look.
Soon you won't wonder - you'll know that whatever you're going to see is going to cause you pain and confusion. You can skip that bit. Soon enough you won't even be curious.
It may has well been a link to monkeys eating their own shit for all of the meaning that it has to you.
That's how you need to treat this kind of thing.
Fake it till you make it. I promise you it won't matter one little bit once you reach indifference. Oh, except you might share it here so we can all have a good laugh about his idiotic antics.
After S I had a whole bunch of people telling me monsters FB was showing all of these soppy songs he was listening to. One of which was a tragic 80s song called "Human" which basically said 'I fucked around because I'm only human, won't you forgive me?'. Apparently he posts quite a bit - more venty these days. I think its hilarious.
I don't let anyone tell me anything about him now because THAT stupid song was added to my list of triggers. Any song by that damn band too. I don't care for any more triggers, thanks.
It doesn't burn any less whether its something nasty or 'nice' - its all nasty when you consider the source.
Don't let the curiosity get you next time. It will take all of your willpower when you first do it but soon it becomes as easy as breathing.
Don't let him into your headspace to roam rent free - he has been evicted.
Repeat until it sticks.
