Here's the scoop. I'll make it quick. My now ex, met a friend over a dating app (they were not interested in each other, just friends). My ex invited his friend over, they drank, and he crashed at my ex's place for the night, on the same bed. They did not do anything, and I trusted that what he said was true. My ex tells me what happened the next morning (like it was no big deal), and I told him that what he did bothered me. We argued, not surprisingly, but his stance is that he had fun and thought there was nothing wrong with what he did, so there was no need to apologize to me. He didn't care about how I felt in this situation (something he clearly stated). If I did something similar like my ex, he says that it wouldn't bother him. The thing is, I wouldn't even think twice about doing that. I just don't think that's appropriate (although, if that was the only bed, then go for it, but there was another upstairs). If I'm insecure, I want to work on that. I have trust issues, and so if you gain my trust, you're a pretty important person in my books. Cross me, and it's going to take a miracle to trust you again. I need a unbiased, honest second opinion on what you guys think!
