Well,within non-binary feelings theres usually a lean of pronouns you wouldn't understand so i'll explain EX:a friend of mine is non-binary BUT if they had to go by either male or female they'd choose female pronouns so in the case they lean on male pronouns that makes you both in a "straight" relationship and in the case they lean on female pronouns that makes you both in a "lesbian" relationship if they cannot choose then that'd make you both in something called a "pansexual" relationship where personality is preferred over gender
