Search Results: girls asking for phone numbers

There was a girl in highschool I talked to only in one class, she seemed kinda strange and I thought she was into me. She was decently attractive but in highschool I don't know what I thought about and she seemed strange. As everyone knows after school groups and all that die out. And I seen her at work once and messaged her on Facebook just asking how she was. She talked a little while then immediately said we should catch up sometime. Now I know old friends who talked a lot this would be normal, however while we got along we didn't talk THAT much, one class that was it and anyway she seemed interested and careful the way she talked, when I mentioned I would actually meet in person she replied 'well only if you want too' etc not dismissive but careful and so I posted my number saying it was in case she needed an easier way to reach me, she said she'd save it and I just said text me your name etc you know contact stuff. But she never did, she kept messaging on Facebook. Not a big deal and probably me overthinking it-but does this mean she isn't interested? I mean girls if a guy you liked have his number wouldn't you text it once to give contact at least? However on the flip side she was the one who said we should meet in person etc so I don't know what to think.
