Love and sex aren’t always the same. You can love someone without having a fierce chemical attraction to them. You can be sexually attracted/aroused by someone that you don’t love. One does not always include the other.
It’s basically our journey in life to not only find happiness with ourselves, our friends, our families, but also to find that one person who embodies both qualities where you’re madly in love with them and they’re the one person that can turn you on more than anyone else.
Loving someone doesn’t mean they’re the one you’re in love with. It doesn’t sound like you’ve found that yet. Bigamy is not the answer. You really think you’re going to be happy for the rest of your life living with one person and then having a back up person to fuck because the first person isn’t sexually fulfilling for you? I think you deserve more out of your relationships than that and I think they deserve more too. I’m glad you’re honest about your actions with both your partner and your friend. That’s something. But I think you need to realize that there’s something missing in both relationships and you can’t combine them to make up the perfect relationship. It won’t work. It’ll end terribly with both of them because inevitably something will go wrong, someone will get too attached, jealous, hurt feelings, lying, betrayal, and then what are you left with? No partner and no best friend.
It never works.
