Valora,

Deep down I know that it does squarely sit with the person who was unfaithful, I feel much better nowadays than I did when I submitted this topic (I owe this to Tiny Buddha, especially those who have responded to my original post). I still feel a little bit guilty but I think this will fade in time.

That is really good advice – I actually did this on a social occasion a few nights ago. I decided that I would drive, had one alcohol drink throughout the whole evening and I had a great time with no feeling of regret the next day! I have some Christmas parties with work in the pipeline, so I think that I will drive, have just one drink and then head home when everyone begins getting a bit too merry. 🙂
