<human>: Give me a shortened version of the text

So I told boyfriend on Tuesday night. I was disproportionately nervous so boyfriend possibly thought it was something worse. But yeah, told him, he essentially said 'you were clearly REALLY worried about that, it's fine. You know I see things in the past as done and not that important'. And then when he saw I was relieved at his reaction, asked if it was ok to start making jokes about it. 

The next day he said  'By the way - I don't think [best friend] can be my Best Man anymore'.  For context: him being Best Man is something of a running joke which my boyfriend has liked because he'd be on the wrong side of the Wedding Party. Also we're obviously not in the ballpark for marriage at this point. Either way I'm glad the joke has been killed! And everything is lovely!

This is a very un-dramatic update post, sorry/yay?
<bot>: Told boyfriend I slept with best friend years ago. He's enjoying making jokes and is fine with it. I'm clearly very lucky to have someone so reasonable!
