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

My girlfriend and I have been together for about 2 years now. We're both in our 20's. I can honestly say that she makes me the happiest person in the world. She supports me in everything I do in all ways. I love her so much, theres nothing else in the world that makes me feel as happy. 

Now I'm probably gonna get a lot of hate for this, but there have been recent complications. As far as couples having issues in a relationship we're about as average as any other couple. Recently at work I've befriended this co worker. Her and I seem to have a lot of things in common. Now first let me just get one thing straight; I am NOT A CHEATER! I've been cheated on in the past and that is one of the shittiest things you can do to a person.

Anyway, we've been working together for quite some time and gotten to know a lot about each other in the process. She has a boyfriend as well. I just can't shake this feeling that we both have this connection; I can sense this chemistry that we have and in a way I think she does too. 

Im not one to make bold choices and I am happy with my girlfriend. I just need advice on how to go about dealing with these feelings.
<bot>: I sometimes feel mismatched with my girlfriend of two years. Im still very happy with her but me and my co worker are starting to have a connection. How do I go about these feelings?
