He didn't ask your permission first?
i guess I'm old fashioned. I don't even know if people still do that stuff anymore.
I took my (at the time) GF's parents out to dinner and asked their permission to marry their daughter. They said yes. Took her to Hawaii for her birthday and proposed. 10+ years ago
Our's did. They had apparently 'spent some time just looking at rings' prior, so my daughter knew something was up. But he asked permission before formally proposing.
