If you hold secrets and do not tell the whole thing (even the most disgusting stuff) to your SO… then it means that s/he is not that “special” anymore.
I mean, a relationship is never meant to be one-sided, but a “You and me” thing. And if you don’t think like that, then you are doing it wrong.
“So you are telling me to just throw random disgusting stuff to my SO?”
No. Call him/her in particular, “Hey can we talk a bit?”. It does wonders, that is all I can say about it.
t. Used to “play the tough guy” back in my early years. Took the “My life is an open book” route. Never looked back since then.
