<human>: [UPDATE]
Thank you so so so much for each and every response. There are so many perspectives here I didn't consider, and that's exactly what I was looking for when I reached out for help.

I'm not going to post a "decision" because I would like to think through more, and I honestly still don't know what's going to happen. I'm scared and nervous, but it is incredibly heart-warming to read your encouraging words and thoughts during a time where I've felt extremely alone.

Thank you, thank you.

I've been dating my now fiancee for over 6 years, and we've been engaged for a little over a year. I love her so much and she's been amazing to me. Obviously, if I didn't feel like this, I would never have proposed.

Throughout our relationship, I've never felt like I've been *really* attracted to another girl. But recently met a girl few months ago who somehow is tugging on my heart strings. This is literally the first time I've ever felt this way for someone besides my fiancee in the last 6 years.

The thing is I hate cheaters, and I don't want to ever do that to my fiancee, but part of me wants to pursue the new girl. At the same time, I don't want to lose my fiancee who has been everything to me. I feel like a total scumbag, but can't shake the feeling for everyday for the last few weeks now.

Does this sort of thing happen for long-term relationships? Does it eventually pass? Did I rush into a proposal - or is this some sick version of cold feet? Is this normal?
