Girls would you send a card and sign "Love, (your name)" to a guy you were just friends with? Or do you like him romantically?

This girl I have known for about 6 years. She's best friends with my best friend's fiance. So she's in our friend circle in a way, but she's not a great friend of mine. Meaning it's not like we talk often at all. But she's in my friend's wedding and so am I. I've always really had a thing for her. She has been over-the-top excited for me since I bought a house. Like way more than usual. She even MAILED me a card and signed "Love, (her name)" and a gift card. My friend has said she has been dropping hints for a while and I've been missing them. Girls, would you send a card like that to a guy who wasn't a great friend, maybe you were romantically interested in him?
