You don't know what I told him. I simply said that I didn't share all of the details because it's my business. You don't know what I shared or didn't share and you don't know what was said with the ex. At the end of the day my ex knew that I didn't want to get with him and I was leaving the wedding with the man that I came with. Calm down dude.
I'm calm (I don't think I gave the impression that I was upset or anything), and I never claimed that I knew what you told your boyfriend or ex.
That's why I'm ASKING about what the details were, and I'm asking if the case was that you didn't tell him that your ex tried to hook up with you. You don't have to share those details if you don't want to.
But if I was your boyfriend, I would find it unusual that you feel okay with telling me that you talked with your ex, but didn't mention all of the details. As I said earlier, the only details that conversation SHOULD have had is him trying to talk about your old relationship/old feelings, and you shutting him down; nothing else. But then again, you said that those details (whatever they may be) are 'your business'.....something in itself that would cause worry to any normal person in a relationship.
You also said that the conversation gave you 'closure'. I would find that worrisome if I was your boyfriend (assuming you even told him that). The word 'closure' implies that you had unresolved feelings for this ex of yours, which no boyfriend should have to learn about in a legitimate relationship.
