Summary: don't trust anyone. No matter how long you've been together.
There's an askreddit going on now asking why you cheat on your SO. One guy posts that his wife doesn't fulfill his sexual desire and he feels like shit, another has a wife in a coma and admits he fucked up by messing around with her sister, then this:
My current boyfriend was my first everything - kiss, sex, cuddles, etc. We've been together since i was very young, and i think we're going to be together forever. I went through this phase where I would go to clubs and make out/grind with other guys, I know he would have considered this cheating, but I was just afraid of missing out on all that experimentation that other girls get just because I met a good one early in life. He's older then me and had been with over 20 girls when he met me, so he didn't miss out. IDK it sounds petty... but you watch HBO and feel like you should get all this sexual adventure before you settle down.
I know he would've considered this cheating
Oh only "he" would? So you don't? Of course it's followed by a "but"
but I was just afraid of missing out on all that experimentation that other girls get just because I met a good one early in life
Just because? Just fucking because? Isn't that why you girls go out? To try and find "the one"?
The nerve of some people is just disgusting.
