<human>: My girlfriend of 4 years and I are in a long distance relationship. I love her, but the distance is getting hard for us. We have talked about marriage and future plans which makes this harder. 

I have recently started volunteer work at my local horse stable, and there is this girl who I started to talk too. After a short while we were flirting back and forth. And she invited me to her house to watch some movies she had and to show her own personal horse. I told her no at first saying it wouldn't be fair to my girlfriend, but the next week I went over and we talked a lot. Just about random stuff of life and horses. 

So the thing is I'm really starting to like this girl but I don't want to hurt my current girlfriends feelings.

Can you give me a shortened version of the text?
