<human>: Can you condense the text into three sentences or less?

A few weeks before my friend's wedding, he and I are out drinking and he admits that he has had a crush on me for a while. We go back to my place to talk and end up kissing and cuddling overnight (his wife was out of town handling some wedding details).

We continue to sneak around to kiss/cuddle/hold hands (we never had sex) until a few days before the wedding when we decide we really need to stop being terrible people and start getting over this.

He obviously recognized that getting married while you simultaneously have feelings for someone else was not, to put it mildly, ideal. But to cancel a wedding to someone you love at the last minute would be awful and devastating to all the people involved.

Since the wedding, we have continued to see a lot of each other (we are in the same program in grad school and share a similar circle of friends so it would be next to impossible to avoid each other entirely) We haven't been physical (except for some hugs), but there are definitely a lot of feelings still there and we are both concerned because they are not going away. He told me the other day that he wished we would have dated and he thinks about it a lot. I feel simultaneously sick about betraying his wife (who I genuinely really like) but also feeling heartbroken about a relationship that could have been.

Any advice on how to make this situation better would be much appreciated.

P.S. I know I'm a scumbag for getting myself into this in the first place. Believe me, I am well aware.
