IDK I could be totally wrong so take this with an enormous shake of salt given that all I know of you is what I've read from your articles and I don't know you in real life.

It seems based on the articles I've read from you that you have a deep fear of being alone, and so being in monogamy makes you anxious because if you get broken up with, you are alone. Whereas in polyamory you have multiple "backups" as it were.

In my experience with other polyamorous people they are ok being alone. And it's more about having an abundance of love to give and not wanting to be artificially restricted by monogamy. But it's not like being with one person or being single is a bad thing. It's more - if you happen to meet other people that you also love, then you can explore that too. Rather than getting bored with who you're with.
