Okay, im on a right fucking guilt trip in which i seriously pissed off my best friend, whom i've known since, well forever basically.
It's all to do with his younger step-sister. My friend only met this step sister a few months back, but his parents are insisting she hangs round with him and thus us. Anyway, because of this she is really pissing him off, he has told me many times how annoying she can be about her appearing and kinda taking over a bit. But she is an outrageious flirt, and her attentions are aimed at me, her friend on the other hand is also completely obsessed by my other friend.
I dont really help much, because i flirt with her too, and being honest i kinda fancy her a bit. But my friend, is very against this, he insists i tell her to sod off, which i have done a few times. But today, when we were watching a film at the cinema, me n her were cuddlin, holding hands and stuff. I didnt think much of it, but my mate, at the end of the film, was seriously pissed off, he didnt make a direct confrontation, but i could tell in his face and his silence that he was angry at me and her. This of course sends me on a right guilt trip and im ashamed of what ive done. But theres alos other things aswell, she is at least three years younger than me (im 16), and my friend tells me of her apparent slagishness, he told me once she was going out with two 17 year olds at once. I know i shouldn't have allowed this to happen, but i don't know what to do. I managed to piss off my friend, im on a guilt trip and ashamed, and she doesn't know wtf is going on.
