However, my girlfriend told me she had shared her bed with a long time ex-lover last week while we were still together. And honestly, having strong issues with your partner choosing to share the bed with her ex when there’re other options isn’t unreasonable. It was literally two people using the same bed and honestly, that’s not really that big of a deal. Now the question that’s hanging around like a fart in a closet is: did she f--k him? The question of “Is it ok that she shared a bed with him?” is an edge case.
