super annoyed

I've been having a bad day and now my SO had a friend over drinking then his friend came in and said bye so I thought he was just leaving he's like no we're going out for a bit but we won't be very long at all. I was annoyed and said whatever. Now they've been gone for an hour. An hour might not seem like but when you say it's going to be quick I don't think of an hour as quick. Also because my SO isn't even the one who told me they were leaving, his friend did. And I'm more annoyed because we haven't had sex in forever, and I said something about it last night and he said well we can do it tomorrow. Guess what we haven't done and won't do? I'm seriously so f***ing annoyed.
