girlfriend troubles Options

[clahky]

I've been dating this girl for over 2 years. Ever since i met her she's been amazing, shes the one girl i want to be with for the rest of my life. For a bit of time, she's been asking me if im "hurting" her and i can't lie to her because i love her too much. A long time ago i looked at other girls naked, not for a while now, and the other day she got me to admit that i occasionally check out other girls at school. I go to college and i sort of subconsciously look at other girls, i dont necessarily check them out and think about their bodies, i just look sometimes without noticing. Now she asks me everyday if ive hurt her, and i cant help but say yes because i see a girl walking down the street and i might acknowledge if shes cute or not. Its impossible to go through a day now because im thinking about it so much, im afraid every day because its like when a sign on a door says dont open the door, you want to open it right? This makes it impossible. I love this girl so much though, and i'd do anything for her to stay. I dont wanna lose her because she really is everything to me. I dont know how to handle this...
