what is more important, my heart or my brain??

I'm not that young any more, I don't have really any time to play or to spend money and time for nothing. I'm 37 and I past over a year in a very strange relationship. I don't want in this moment to explain many details but just she was a prostitute and she stop after our beginning. The point is not exactly what she was and what she did, before or after she was with me. I need a advice about what I may do. Turning back to what I past with that girl in the last year and more, trying to understand what makes me love her, or if she deserves to be my family and why do I love her, in this point I just don't have a real answer. What connect me to here is just a sexual perfection but nothing makes here able to become something more serious in my life.
But it's over three months we don't live together any more, I can't forget her, she calls me often, ask me to come back, I saw her a few times, I'm getting bad any time I see her, I drink alcohol and blast to her.
I know is something utopian to believe I may have a normal life and family with her, because of her previous life, of her actually life but my question is: does a chemical connection, may love be more important from anything ales and can make me really happy just because I follow my heart and I didn't listen to my head? What is more important, what does my heart says or my brain orders me to do?....

 

your feet are the most important.. walk and keep walking..

 

thanks for the replay, I really appreciate it, but I don't get you at all..

 

Not your brain because you posted this twice.

 

So true ...

 

Forget what she did and follow your heart. Your brain will deprive you of potential happiness.

 

that is true, but that looks some too romantic, isn't it? but I'm thinking I am following my heart more than my brain... never mind.. thanks for your advice..
