Search Results: is he attracted to me marriage

I'm a girl, he's a guy. We're police officers. We've been best friends & work partners for 7 years. He's been with me through a divorce, a near fatal car accident & then the birth of my child, I've been with him through a divorce, the depression that followed & recently, a marriage. He's the most loyal, honest, moral man i know, until now. The thing is, we've always been respectful, he's always been attractive to me but I never acknowledged it & he did the same. For 7 years we were perfect sibling like friends. Well, last year he was drinking & we were texting, as usual & he told me he used to think about marrying me & that he's been attracted to me since the day we met. He began to name times, conversations & events that were significant to him. He told me he wished we would have gotten together & he regrets not speaking up. I was but overwhelmingly flattered. I confessed that I felt the same. Since then we have engaged in a fantasy "what if" relationship, complete with sexting. The issue im having is this, he remarried his ex wife a week after he confessed to me. They are trying to have a baby. I am in a ltr with a man who is not very good to me but I've never cheated on him or considered it until now. My best friend wants to have an affair with me. I want him, I would love to be with him because we love each other & want each other so much. I dont know how we could be detached though & I'm not sure who I'm more concerned about, him or me. I realize how selfish this is, we both agree that the right outweighs the wrong. If we do this am I going to lose my best friend? If we don't do this will he find someone else? I'm confused, kind of.
