aahhh, TIGHT SITUATION!!!

for me this is a very very tight situation...ok, i am going out with this girl, but she is a girl which is in a group of friends at school, and i am in that group of friends too, so i dont want those ppl to think bad of me, and i also dont wanna hurt her too badly. i just want to tell her how i feel now, and b4 she told me when b4 she dumped someone, and she HATES not doing it in person...so i wanna make her happy and do it in person, tho i know its not making her happy, but it will make it less stressful or unhappy for her... and idk, its just hard... please help!!!! thanks...
