I don’t know how to feel about this gift

So I 38f was gifted an expensive blanket from my situationship partner 50m. I guess it’s a situationship as we never defined anything and it’s been like 6 months. Yes…I know. He wrote me a note that says “thank you for being a part of my life. You make me happy!” With love, X

I don’t know how to feel about the gift. Who gives their situationship a gift like that. Does he want more but not communicate it? It’s making me nervous. We’ve told each other we like each other and we care, but it’s like we cannot move past that barrier or even talk about it. I’m just going to have to suck it up after this gift and have a discussion. I don’t like ambiguity
