I know this was over three years ago for you, but hear me out. My advice to you is, l*ve while you can. Now you can interpret this two ways, live or leave while you can. You do love her in some way. An arrow isn't just point out of the sky and tell you who you're supposed to be with. So you go to the person who makes you feel what we call love and you finally say it, "I love you." Except, you phrase it as a question... and she takes it as fact... and then there she is in front of you... standing in a three thousand dollar dress with tears in her eyes... and her nephew made the Hupah so what can you do? What do you do then? Say, "I was kidding?" No, you live right? For the next few months, you stare at the alien form who goes with you everywhere and ask yourself "Who are you?" Then one day you accidentally say it out loud. Even if the relationship ends on a particularly unhappy note, wasn't it better to have lived than left. Do yourself a favor and don't be like me. You love this girl so much it causes physical, tangible pain. Live while you can.
