<human>: So I have been dating my GF for 4 years (almost) and things were going great. We had talked about marriage, kids, you name it. But, that's when my friend (lets call her T) comes in. I met T 2 years ago, and I thought she was super attractive, but never did anything about it. As it so happens, we got into the same dentistry school and now we will be spending the next 4 years together in a class of 28 other students, about a 4 hour drive away from the city where I am from (and my GF). 

So now I spend a lot more time with T. She is very friendly and talkative, so I flirt with her every now and then, but initially it was never with any intentions. Two days ago, I was drunk, and we made a pact to get married by 28 to each other if we both happen to be single at that point. And I also told her that night that I haven't been happy in my relationship. She told me that I should not talk to her about this (as it would get her hopes up) until I figure everything out, which makes sense to me.

So now here are my thoughts. My GF is great, and I do love her, but I think it is possible for people to love each other and not be meant to make it the whole way. I can see myself with my GF in the immediate future, but I find it hard to imagine in the distant future. Whereas with T, I can definitely see it going all the way. It also helps that T is the same culture and religion to me, two things that are very important to my parents. I know they wouldn't say anything if I married my GF, but I know deep down they wouldn't be very happy. Me and T also seem to have a lot more in common than I do with my GF. But at the same time, I feel that I have gotten so close to my GF and her family that I cant imagine my life without them either (in the near future at least).

Somebody please help me.

Can you give me a shortened version of the text?
<bot>: I have a GF of 4 years. I believe I am getting feelings for another girl (lets call her T) and I love spending time with her. I do not know where to go from here.
