<human>: I am in a relationship with my girlfriend whom I love very deeply. I also love my very close friend, and would like to be with both of them in a ploygamist relationship, however I withhold the urge to try and bring them together in such a relationship as it conflicts with my long held loyalty to my girlfriend. We have been together for 3 years. I feel that if I tried to bring them together in a polygamist relationship they would both resent me or worse not want anything to do with me. 

Ive broached the subject very lightly in the terms of a one night sexual venture to my girlfriend leaving out who the other would be, and she was profoundly hurt by it. Neither of them know this side of me, and I am very careful to keep it that way. They would just be the perfect duo to be with, and would like to know if I should just lock this away deep within the confines of my subconcious, or if I should act on it and if I do how should I do it?

Can you condense the text into three sentences or less?
<bot>: I want to be with both my girlfriend and my close friend but am unsure if i should act on it and if i do how i should go about it or if this is just something to keep locked away.
