<human>: Can you succinctly summarize the text in 1-3 sentences?

Ive been with my SO, we'll call him Rob, for a little over two years, and things have seemingly been fantastic between the two of us for that entire time. We've been living together for a lot of that time, and its been the best experience of living with another person I've had. Although, we have spent a great deal of time with one another, and thats not something I'm used to or necessarily wanting at this point.

So I work a seasonal job during this part of the year, and have for quite sometime. I met someone there, we'll call him Jack, and he absolutely took my breath away after talking with him for only about 5 minutes or so. We work together pretty often, so I see him quite a bit, but even when were not working together, I cant get him out of my head. I've known him for little over a month, but have developed quite the infatuation.

I didnt ask for this! I have been happy with Rob, and he loves me unconditionally, but it feels like he loves me more than I love him and I cant help but think that it isnt fair that way. I think I need to end things with him, but I dont want him to think that I'm leaving him for Jack because I'm not. Jack only helped me realize a lot of things that I wasnt happy with. 

I know this post isnt very detailed, but my mind is constantly racing, its hard to form a coherent sentence and I need help. Feel free to ask any questions you have, and please, any and all advice is so appreciated. How do I tell any of this to Rob, without him feeling like he did something wrong or that I don't care for him?
<bot>: I think I fell out of love with SO after meeting someone else, not sure on if I should end it, how I should end it, or why. Please, help me!
