DEAR JANE: I committed a heinous betrayal at my bachelorette party... then I vomited mid-act!

Dear Jane,

My partner and I have been together for three years and got engaged six months ago.

Last weekend was my bachelorette party, and my maid of honor - my best friend from childhood - planned the whole thing.

She decided to host the weekend in our hometown, which has a few fun bars and clubs to go to.

So on Saturday night, after a full day of drinking, we hit the most popular club in town.

There were ran into a group of boys who went to our high school, including my ex-boyfriend. (Alarm bells!)

I was very drunk and clearly not thinking straight - and my when friends joked about how 'iconic' it would be if I hooked up with my high school boyfriend at my bachelorette... I drunkenly agreed.

I woke up the next morning in my own bed - alone - with very little memory of what had happened, but my girlfriends quickly filled me in on the night.

Apparently, I made out with him on the dance floor in front of everyone, in a kiss that only came to an end because I had to throw up. Afterwards, luckily, I was taken home by my friends.

Of course, I feel awful for kissing him - but it was JUST a kiss, and I really don't think it's necessary to tell my fiancé. I've never been unfaithful before and I will never be unfaithful again.

But there were so many spectators and everyone knew I was engaged (I was wearing a 'bride-to-be' sash). I'm scared the word is going to get back to my fiancé and that he's going to be doubly upset because I wasn't honest with him.

I'm also upset with my girlfriends. They encouraged me to cheat knowing that I was blackout drunk. Perhaps I could tell my fiancé what happened, but tell him my friends forced me to do it. Would that be wrong?

From,

Bachelorette Betrayal

Dear Bachelorette Betrayal,

What you did was certainly silly, but it wasn't terrible.

Given that you were very drunk and have no memory of what happened on the dancefloor, I think perhaps you need to be a little more gentle on yourself.

Please be assured that a drunken kiss that ended with you throwing up is not what most of us think of when we think about being unfaithful.

With that said, as hard as this may be to hear, you will feel a whole lot better if you come clean.

Embarking on married life carrying a secret is no way to start a healthy relationship.

Tell your fiancé the truth. 

Explain that your friends were encouraging you to misbehave, and that you were not in a position to make an informed decision. You allowed an ex-boyfriend to kiss you and now you feel awful about it. 

I really don't think one drunken kiss qualifies as infidelity and I imagine that, ultimately, your fiancé will see things the same way.

As for your girlfriends, I'm guessing they were as drunk and silly as you. I think you should grant them the same grace that you are asking for from your fiancé.
