So let jump straight into things. So i am 22 years old and have a girlfriend of 6 months and to be honest i can't love her anymore than i do. she is my world and i can't see my life without her... i just want to get that out of the way first so i don't come of as more of a bad guy than i'm already about to, here goes. So i have a massive crush on a childhood friend.. she is just everything i don't want in a girl and i honestly don't see the attraction, but over the past few weeks i have been having really impure thoughts towards her and even struggling to sleep over it. She brings out the worst in me, i don't often get into bother with anyone or anything but when i'm even just hanging with mutual friends i find we flirt a lot I honestly don't know what to do.. i refuse to break up with my girlfriend and as much of an ass that i feel and sound like i am but i just don't know what to do because every thought process i go through seems to bring me further and further down into a slump and makes me feel like the worst possible human being. I don't want sympathy as most people on here are either going to think i'm a douche or just a generally bad person.. but we all have emotions and they don't always make sense.
