Love Triangle, help me!?

I'm stuck in the middle of this horrible love triangle; I have these two guys (on of which is my bf) now don't get me wrong I care about 'Hatter' (bf), but with him there's no chemistry, I mean as a friend he's ok, but as a bf he is not everything I was expecting.He told me that he prayed for us before he made his move, and that we are destined to be together, but he does nothing, we barely talk or see each other, and when we do talk he doesn't talk to me still he's dead silent. I feel like I'm being ignored in this relationship, but I do care about him and I don't want to hurt him. Not only that his sister is my best friend and she is the one who encouraged it. I feel like everything's a simulated, catalyst relationship. BUT in the midst of all that there is this guy lets call him 'Rabbit', and he is just...you get the idea. We talk all day everyday and he makes me feel like 'Hatter' doesn't, he's attentive and loving, and affectionate. He also prayed about this situation and only wants whats best for me. With him everything is so natural, I mean the chemistry is so amazing! Our conversations just flow and are so in depth. I love how we can share our philosophies on life and just vibe to the moment. Its like we're drawn to one another so strongly, that the fact that I'm involved with someone else seems irrelevant. I really think I'm falling for 'Rabbit', and I know he's fallen for me, I just don't know what to do, I don't want to hurt anybody, but sadly that's the reality of this situation. I honestly think that 'Hatter' suspects something because the last night we spoke and he expressed his concerns about me leaving him, I started to tell him about 'Rabbit' and how I've been feeling lately, I really wanted to, but he started to cry at the thought of me leaving. I've never been faced with this before, 'Rabbit told me that 'Hatter' must feel guilty... I've been praying for days about this situation and I think Ive reached my decision but I don't want to regret anything or hurt anybody. Please people give me real advice, nothing on bs plz thnx n have a blessed day
