I really like a girl, in fact I would go as far as to say she is perfect, beautiful and I get on with her really well. Problem is she has a boyfriend and has done for quite a while. I have never really made a move on her because it didnât feel right. While away on holiday I heard she slept with another guy it was nothing really but a holiday fling but I am fed up of waiting around to see if she leaves her boyfriend. I am considering anonymously telling him....... what do you think of this? Is it totally wrong or just a little? My biggest worry is if it worked and we got together eventually I would always have it hanging over me that it was me who told her ex. But then maybe I am doing them both a favour.... right?
