Does your boyfriend have a reason to be upset/suspicious? You said that you wanted to just "let him vent" and I'm not sure what that means. If the condoms weren't yours - or were, but there was no illicit purpose for them - then you don't need to sit and take any verbal dishing from him. He has no right to hold anything over your head, unless there is something to be sorry for. So, without knowing that history, it's a little difficult to advise you correctly. Can you give me a bit more information about the situation?
