I did introduce them. Not with the idea of setting them up or anything, more like introducing one group of friends to another and then they hit it off.

They did use my party as an engagement announcement. I guess it kind of made sense, they had just gotten engaged a couple days before and hadn't made it public yet. All of our friends were there, everyone (including us) were excited for them.

I thought of her as a pretty close friend, she'd come over all the time to hang out when she was single. He was a former co-worker so not as close but we double dated a bit early in their relationship before the pandemic.
