I am in a very happy relationship, and I drank so much I slept with someone else. I need advice.

My partner and I have been together for over a year and a half, we’re both very stable and happy in our relationship even though it’s long distance.

I went to freshers week yesterday with my Uni friend and of course we had drinks there. I had quite a lot and ended up sleeping with a guy I met (he was also drunk and it was totally consensual). I hardly remember it and just realised when I woke up next to him naked.

I feel completely awful about this, I wouldn’t see the guy again but that doesn’t change the fact I drunkenly cheated.

I need to get this off my chest and get some advice with what to do. My partner would be quite rightfuly crushed if he knew, even though I would never dream of doing it sober. It was a horrible thing to do and I feel dreadful. I don’t plan on telling him and my friend says to just let it go and carry on because I was completely drunk and couldn’t really think about what was going on.

Should I just put it behind me? Tell my partner? I don’t know what to do.
