Name changed.
I've been at a new job on and off for the past few months. I'm in my twenties and my colleague (kind of an unofficial supervisor) is in her fifties ish. She knows I don't have anyone to spend Christmas with this year. She invited me to stay with her over Xmas (in a support bubble so all would be safe) and said a lot of things like "I wouldn't say it if I didn't mean it" and eventually after a bit of pushing from my friend (who's busy on Xmas sadly) I sent her an email saying it would be lovely to pop in and see her on Christmas Day. I sent this a few days back.
However, she's not responded to this at all and she's sent multiple subsequent emails to the team so I know she's been online and can read mine. I feel very awkward about the whole thing, as I'm worried she just meant it as a social nicety and doesn't know how to let me down gently. So AIBU to have said yes to it and assumed she wasn't just saying it as an empty idea? I can't imagine anything more awkward than saying something just to be nice and having the other person respond with "yes please!" (or words to that effect).
