So I am engaged to a 29 year old man that I have been with for almost a year and six months-things have been good for us, we have had a few major fights but we know this will be our future. Anyway I recently began falling for my best friend of three years when we were on the phone one night-hes been in love with me for a year and a half, then even more recently I have began falling for (at least it feels like it) one of my friends from college who happens to be a marine. I have never cheated and I have no intentions on it-some days I feel like my fiancé is my special someone, but other days it feels like he's not. I need advice I'm 18, a senior in high school and don't exactly understand how this stuff works...
