(for example, 0 if you are single, 1 if you are in a monogamous relationship, higher numbers for polyamorous relationships)

This implies that you are only poly if you're in more than 1 relationship. I suggest simply

(for example, 0 if you are single, 1 if you are in a monogamous relationship)

because

• If you're poly, the idea of counting relationships will be familiar to you already; it's only those who aren't who might need it set out explicitly
• I hate saying "you have to add more text here to cater to my itch" - if I can fix what I perceive to be a problem by removing text, I much prefer that.
