<human>: Can you succinctly summarize the text in 1-3 sentences?

My friend's wife and I recently started kissing after a heavy night of drinking. I woke up with no memory of the situation, but she called the next day to let me know what had happened. I was petrified and in shock. We're both happily married for over 12 years each, and chalked this up to too much alcohol. 

I called my best friend (different person) and confided in him about what had happened and he advised that it was a mistake and that telling anyone else would only cause a massive amount of trouble between everyone. We are all very close friends (my wife and I, and he and his wife) and I deeply fear that this could ruin everything. We all have families and get together a lot during the summer and holidays.

I thought this was behind us, but over the next two weeks after the incident my friend's wife has come forward and admitted to having feelings for me for a long time. I have also felt strongly about her, but we are both happily married to different people. There was flirting via text and a lot of questions as to how long each of us had felt this way. The more we talked the more we both realized this could not be, and have been trying desperately to simply get back to a friendly relationship with each other. 

We've been trying to keep things civil, and have had multiple conversations in an attempt to subdue these feelings before things get out of control. We have both found this terribly difficult to do and have decided it is best to simply stop talking to each other for a length of time in hopes this will help calm the situation. I'm afraid that we won't be able to keep a friendly relationship with each other. The thought kills me because these people are some of my closest and dearest friends. I know we will end up ruining each others marriages by continuing to move further into a more intimate scenario, and I fear that we won't be able to be around without thinking of each other as more than just friends.

Is there any way to salvage these relationships, or do I need to cut off ties in order to save both of our families from destruction.
<bot>: Friends get drunk and make out with each others spouse. Find out there are strong feelings between each other, stop before things go too far. Trying to salvage friendship without the kissing coming to light, ruining multiple friendships and family relationships.
