Hey there, hope, and welcome to PsychCentral. Sorry for why you were googling, but I'm glad you found this site.

I would be feeling much more betrayed by your guy's excessive drinking--which is all that led to the kiss, right?--than by the kiss itself. I'd say both the health of your relationship as well as your own safety were both threatened by his drinking.

Even if this were the only such occasion, I would still worry more about the drinking. From what you say, without the alcohol in the picture the kiss wouldn't have happened.

His kissing another woman seems to be the issue because it stirs such high passions, but if he doesn't drink again is there any reason to think there would be another kissing incident?
