I think your insights are trying to get your attention.
And from a single writing I'd suspect that you may well be one of those people who are just going to be 'poly inclined' all your life. No way of knowing where that came from.
But you are seeing the evidence and need for balance in your life. It's extremely rare that any one person can fulfill all our various needs for connections, shared passions etc. The broader and more complex you are the harder it becomes.
And I think this realization is something that pulls a lot of people off the mono path. For those, it's just not a good fit. Always going to be a struggle with a lot of bitterness and resentments bubbling under the surface. Not the best way to live.
Keep thinking, talking and learning. Trust your insights - especially when the are substantiated.
