<human>: Can you provide a brief rundown of the text in within 3 sentences?

We spent 10 really good months together.  I had met her slightly through a mutual friend and we started dating right away.

2 months ago I found out something that at first I didn't believe, mulled over whether I really believed it for about a month.  Confirmed it was true and have for the past month been trying to see if I can live with it.  I can't.

Try as I might it bothers me to the point where I can't get past it and honestly I'm tired of fighting with myself everyday.  I know intellectually that it shouldn't bother me but it does so I need to put an end to this.

Now how can I do this without hurting her as much as possible.  My first thought was to tell her its me not her, but I know how cliche that sounds.

What should I say so that I am as gentle and respectful as possible?

Just fyi I wasn't going to put the reason on here but I guess there is no way to help me without knowing.

Found out she was a stripper who not only stripped but actually would perform extra services away from the clubs.  Source: she gave my cousin head in a parking lot.  He knew her immediately when I brought her to a family event, she didn't recognize him but did say he looked familiar.  I was able to find a website of club she worked at and sure enough they have a video up of her dancing (fully clothed at the time).

Anyway, not going to work for me for many reasons.  How can I do this and still be respectful?
<bot>: found out current g/f was stripper (she never told me this) and performed extra services.  This is a deal breaker for me and I need to end this as respectfully as possible
