<human>: Can you give me the gist of the text in a nutshell?

Ok guys, I have been around Reddit for a little just browsing threads from time to time, but I have never jumped off the deep end and actually posted something, so here goes nothing. 

I have been in serious relationship with my significant other for nearly 1.5 years now, and everything has been pretty great. She is attractive, smart and her family is awesome. Some may ask why her family makes a difference, its because I don't have much of it.

Anywho, we recently moved in together and I have been nervous about that for quite some time. Move in was great all was well, until I went away for the weekend. Over the weekend, I ran into this beautiful girl, through some mutual friends. Honestly, my current girlfriend is far more attractive, BUT, we seemed to click extremely well. We didn't do anything and nothing happened as I would never cheat on my girlfriend, but we hung out and talked a ton and I honestly really like her. 

The problem here isn't the fact that I like her or think she is amazing, it's the fact that now I am second guessing everything I ever knew about my relationship. After coming back, I can't stop thinking about this girl, even when I look at my girlfriend. I can say with 99% honesty that I may never see this new girl again because we live so far away, but this conundrum has me questioning my whole relationship now.

If only one girl that I met can make me feel like this, should I not be in a relationship? How many other people are out there that could just be passing me by? It is because this is something knew and exciting? I need some help here as I am honestly on the fence of breaking up with my girlfriend and I just have absolutely no clue of what to do.
