I’m a woman in an 80% male profession fwiw. I’m trying to put myself in her situation but obviously all I have to go on is what you’ve said here.
I end up at 2 possible things:
She really wants to learn the work and do it on her own, but she’s still not confident enough to not have someone check her work. She can ask you questions and not feel judged in front of her co-workers at a new job. That’s huge - no telling what her experience there has been like so far. Additionally, while you’re there if any fires pop up, she can count on you to help while she’s genuinely trying to get better at the job herself.
This does not mean that she’s not interested in you - just that her #1 priority is her job performance right now and she’s doing what she has to do to make that happen. It doesn’t mean she’s using you in a malicious manner.
She does like you, and there could be some of #1 mixed in here too, but she doesn’t want to be too obvious in front of her new co-workers and/or have a relationship with a co-worker at a new job. It could make her look like she’s doing it solely to try and get ahead, something that women do get accused of. She probably feels awkward and doesn’t know how to behave…she’s afraid that the people she wants to impress will judge her.
My advice would be to continue to help her and be her friend, but also try to figure out what things are like for her at her job. Does she have any coworkers she likes? Dislikes? Find out why. Is her boss a demanding asshole? That could say a lot.
Don’t rush it and let her get settled in a bit. IMO she’ll appreciate it and it won’t be as jarring as “so are you into me or what?”…please do not do that, especially if she’s already insecure about her job.
