I am extremely attracted to my boyfriend's brother... and I don't even know why. It doesn't make any sense, and it p***** me off. The past 2 years, I've done everything in my power to ensure our relationship works. We've finally gotten to a point where we know each other through and through and are connected in every way possible, to the point where he is the one bringing up marriage and settling down... this is the man of my dreams. He treats me like a princess. He gives me the love and stability I've been craving my entire life... then I see his brother. it's like he has this pull on me. He is more good looking, yes, but that sort of thing has never compromised my interest so I don't think that's it. His brother and I don't even talk, in fact we seem to talk around each other i.e. talking to every other person in the room aside from each other, yet every time we are in the same room there is tension or nerves. I find myself wondering if he feels it too, over-analyzing any little interaction we have only to mentally berate myself to not let the thought go further. Reminding myself I have a boyfriend that I have a sure future with and that this is impractical. Wrong. Just thinking about him and this situation now is making me feel breathless. intoxicated. It's like being in middle school, high school even, and feeling the butterflies of a new crush. I don't know what it is about him that makes me want him so bad I barely know him but I want it to stop... I thought maybe if I got it off my chest it would help. I don't want to feel this. I don't want complications. How do i make it stop?
