One Sided Love

Why do I still go back every hour checking his account for some changes when I know he doesn't even bother about mine? why do I keep thinking about what he is doing when I know he doesn't even care that I exist? why do I keep opening his stories when he hasn't checked mine in daysss? why do I avoid him just to go back in few hours? why do I still have feelings for him knowing he would never have them for me? why can't I forgive when he probably doesn't even remember that I exist?Why Do I Love Him When I Know He Doesn't Love Me?!
