Questions: Girl's Behavior

There is an attractive younger woman I meet at my local CrossFit gym a few months ago. After getting into a several friendly conversations with her I one day asked her to get breakfast.

She smiled at me and said “thank you but I have a bf”. I responded that I respected that and I wouldn’t ask again (while smiling). I believed her at the time and appreciated her handling it the best way possible. She was polite but direct. I didn’t pick up on any negative body language.

Since then I’ve ran into her several other times in class (including a small class with just her, me and the instructor). I act courteous. I’ll give a quick hello and goodbye after class. I even occasionally help her rack heavy weights and move machines (I help other people w/ this too sometimes).

However I don’t start conversations with her anymore. I don’t want her thinking I’m okay with a friendzone or stroke her ego too much by giving her additional attention. However I do act polite to her because she was respectful by how she rejected me

But she’s the chatty type and I’ve overheard her get into long conversations about what she is doing in grad school, her vacations with her friends and her weekend plans with other people. Not once has she ever mentioned her boyfriend. Never. I am starting to wonder she gave me a well intentioned lie.

That doesn’t mean I’ll keep trying if she’s single. She’s obviously not interested in me that way and that’s okay. We both know where each other stands.

But I just wonder why she lied to me about having a boyfriend.

Recently, I started dating someone new and we have gotten along very well. We started clicking on all levels, built chemistry and then she asked my body count. I said “only 3” and then she started laughing and said “20.” I then sent her a message the following day about deciding to work on myself and she accused me of being misogynistic and hypocritical “typical guy.” Then called me an “a$$hole.” For obviously rejecting her due to having a high body count.

So this is the 2nd time i got the chance to work alongside this cute coworker who I've catched often locked eyes with me even from afar or alil close up. there's like 2 other woman working aongside us both as well but i notice this cute coworkee playing with her hair like pulling the end of her hair down as to straighten it up. She also strike convos with me asking a few basic questions as to getting to know me better such as do i go to college, how many language do i speak. Is this all signs that she is crushing me too?
