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

I've got an amazing new boyfriend who might just be my dream guy. We are going to a camping event in a few weeks and I'm nervous I'm going to run into a drunken one-night stand. We've talked about our "numbers" and while the one night stand and I didn't have sex (thank god) we did make out and spend the night together about 3 years ago and I haven't had contact with this person since. I also have stopped drinking heavily since then. I regret the entire incident and really hope that I don't have to explain what happened to my new boyfriend, because I'm honestly ashamed of what happened and I don't want him to see me differently. I need some words of advice for a situation that hopefully will not arise?
<bot>: Had a drunken one night stand, Might see said O.N.S with new boyfriend, How do I deal with the situation should it arise?
