<human>: My girlfriend and I have been dating for about six years. She is everything to me. We share the same goals, aspirations and general life philosophies. We have been through a lot together and have come out the other end stronger for it. We are honest, we are physically attracted to one another, and we are going to get married. She gives me space when I want it and is there to support me when I need it. The only problems we have are some bedroom issues - she has no sex drive, but tries to put effort in.

So except for the sex issue, we have a GREAT relationship and I love her dearly. But about a month ago I was hanging out alone with a friend from college. we were always close but it never blossomed into something more than friends. We were hanging out at my friend's apartment, drinking when things became SLIGHTLY physical, no sex, no kissing, no hugging, but there was an air of intimacy in our interactions; our fingers briefly intertwined, we gave one another a massage, but nothing beyond that. I was falling fast. But as things began to get more risky, we would both put an end to it. The feelings continued for the next few days, but since that night, we have both limited communication somewhat.

The problem is that I love my girlfriend, but  I cannot get my friend out of my mind. My girlfriend and I have been through a lot of family and financial issues together and we've always seemed to weather the storm together. Before last month, I had no doubt in my mind that we would get through our lives without temptation.  I cannot seem to muster the strength to cut communication between My friend and I.

Even when I compare the two, on paper my girlfriend is more compatible than the other girl in a number of ways, but there has always been that connection between my friend and I, we just click and we always have.

Question: What do I do? How do I deal with this infatuation?

<bot>: Fell for my friend who I have always clicked with; I am in love with my girlfriend who I am more compatible than my friend in many regards, but can't seem to get the friend out of my head.
