Is it possible to love someone with your mind instead of your heart?

This may sound confusing but I'm confused myself so bare with me okay?

From the beginning: Since as young as i can remember i was attracted to both men and women. Before i even knew what it meant to be attracted to someone. I remember being in kindergarten, in which i got my first suspension. It was for kissing my classmates, i was really affectionate when i was little i loved everyone! I would kiss and hug all my classmates and teachers and i guess their parents complained to the teacher about it and i wouldn't stop, so i got suspended. My first kiss was with a girl and my first sexual experience was with a girl, she was my first bestfriend also. Guys didn't really start approaching me until i was about 14/15, i started dating guys around the age of 14 also having sex with guys around that age too.

Middle: I tried dating girls before but i never felt anything for them like i did when i would date guys. I wouldn't emotionally anyway, I'm very much sexually attracted to woman. I think women look way better than men do, i also tend to date men who are pretty i was never into masculine looking men like that. I've dated 3 girls in my life and they didn't last very long, i would end up breaking up with them because i felt it was wrong to have them fall for me with me knowing i would never fall for them.

End: I'm currently dating a man and we've been in a healthy relationship for about almost 2 years now. I love him, i would go in detail but that would take up too much time, this is long enough lol. Any way, I've recently been sorta of crushing on a woman who follows my blog on tumblr and i follow hers. She is so intriguing, inspiring and just gorgeous inside and out, I've never met her though we talk a lot more than anyone I've talked to on that site before.

Here were it gets tricky: I think i love her.. I can not put it any other way than that. It's different than I've ever experienced though, it feels like i'm loving her with my mind. I cant love her with my heart because it's already full of the love i have for my boyfriend. In other words, he's made it hard to love anyone else than him, except god of course :)I don't feel that spark in my chest i get around someone I'm in love with. With her i just feel the spark in my mind, i feel happiness when i talk to her and excitement, I can picture me being with her if i wasn't aren't already in a happy relationship with my boyfriend. I can picture me kissing her and wanting to spend every min with her talking to her, and holding her, possibly dating her long term. Is this normal, please someone try and explain to me what is going on. Usually I'm good when it comes to things like this but i am totally lost and in need of some advice or direction of sorting out my feelings. Nothing make sense right now!
