Could she be actually interested?

There’s this coworker I started working with a few weeks ago. Before I never had worked with her or talked to her much. Like she started before me but a month in after I started working she had family issues and left for 5 months and just came back. Since she’s back she’s been helping me with my work because I’ve got a lot (our boss wanted her to help me). I’ve trained her on stuff and just message her now and then that’s it’s going okay/if she needs help. Since then she often sends me flirty emojis in messages when it’s just work I’m messaging about or regular talk. Like the smiley face with hearts and the sparkling heart one. When we talk about work the convo often moves to small talk. I wasn’t sure/didn’t think much of it, things like in the workplace can turn bad/get really awkward. Yesterday we were chatting though she mentioned something how two other workers were together I was like oh interesting. Then she randomly asked me out of the blue in a somewhat curious tone if I had a girlfriend. I said no and she said why. She then asked if I had been married before etc. could she be interested? My other coworker (who’s a girl) often mentions to me that she seems like she likes me and she said she isn’t as nice to her as she is to me and keeps giggling about it. At first I just thought the emojis were friendly and thought my coworker was misreading it but when she asked that I’m not sure now lol.

Could she be actually interested?
