<human>: So a little background on us, we started dating in high school.  Both graduated and she went off to college while I continued to work.  The college wasn't far away, I would go see her once or twice a week.  

After the one school year I was able to put together the funds to move up to where she was in school to continue our relationship without the distance.  We are very close, and often times feel very inseparable from each other.  

Another school year rolls by with me living in town and we are having the time of our lives together.  She is an avid equestrian and decided to take a trip to Ireland with her friends to ride horses through the countryside.

Upon her return we have an apartment all lined up for us to move in together. However, she comes bearing the news that on one of her nights at a pub she met a guy.  A guy who she spent the evening with and ended up making out with him for an extended period of time.  She claims nothing sexual happened and I do believe her.

She came back and told me this because she couldn't live with the guilt of it happening and felt I had the right to know.  I of course was sad and angry but I love her to pieces and can't let something like that get in-between our relationship.  So we proceeded with the move and are now living together and love it.

This was three weeks ago and I still hurt about it like its fresh.  I know I probably shouldn't, as it was meaningless.  However I feel like I am such a back door in her life.  She goes to college and I manage an auto parts store.  So I guess what I am asking is how do I get through this?  I want to get past this and feel happy with her again.  Do I talk to her about it?  Do I just keep it bottled and let it blow over eventually?  We envision the rest of our lives together on a daily basis and I can't let this get in the way of that.

Give me the gist of the text in a nutshell
