Could it mean something or not likely?

There is this girl I work with. So valentines day this year was on a Friday. The Thursday before she asked if I was doing anything fun this weekend and all. The Monday after she asked if I had a good weekend/what I did etc. I know she could just be asking that in a friendly way/making small talk. The thing is is she has never asked it before that weekend or even after that weekend. At times she has said or done things that could have seemed to be interest. Like a little after I started working with her she was telling me how two other coworkers were a couple. I was like oh interesting. Then she asked me in a somewhat curious/interested tone if I had a girlfriend. I said no and she said why? She brought it up a few days later on why I don't have a girlfriend/why I don't get a girlfriend. She even asked a coworker what would she happen if she married a guy of my ethnicity (he and her are the same ethnicities-different from me). Like I thought he was joking but he showed me what he sent her (said don't tell her). It was a screenshot of her looking it up online. Just curious.
