<human>: I believe that we're highly compatible, but I worry that the passion is fading. He is an amazing listener, incredibly patient, and just seems wise beyond his years. I can't imagine my life without his support, and I can picture him being a great husband and father. 

I just have this nagging feeling that I'm staying in the relationship with my mind over my heart…I've never had sex with anyone else (though we do have really good sex) and I feel like I could benefit from some growth through being on my own. Yet I also fear the regret of breaking up with him. I've considered trying for an open relationship, but that seems like an ill-fated "solution." 

The last think I'll say is that we've had some really honest talks about my sexual naivete and my desire to try other people. His level-headed and patient response to those conversations makes me love him even more and make my interest in breaking up subside. But then I still have that curiosity about other guys…

Can you give me the gist of the text in a nutshell?
<bot>: I'm in a long-term relationship with my first love, best friend, and amazing person, but I'm curious to try others: should I break up with him or let this run it's natural course?
