Just wanted to point this out...
Could just be that your hinge guy has a certain love vocab/action plate.
Because he does the same type things with you in the newer rship that he did with her in beginning of the older rship doesn't have to mean you are less special to him than the other. It's just his way of going when HE is in love with people.
When I was open I called my loves "sweetie" or "hon" or nibbled ears hello or whatnot... That is part of MY love vocab/plate of actions. It didn't mean I loved A more than B or B more than A. It means *I* am in love and this is how I behave in love.
If you are comfortable sharing and going "Aw, isn't our Hinge Guy so cute in love? He always does that flower thing doesn't he?" that's great. If you are not comfortable sharing and feel like it takes away from specialness, perhaps back up some and don't share so much.
