Advice please

I posted a couple weeks ago about a woman who was new at work. Long story short I had a huge crush on her. She asked for my number and from there we’ve been talking, flirting, we hangout when we can at work, she always comes up to me on our breaks to talk. She always asks to come to lunch with me. Someone commented that I needed to chill out because I had feelings for her and she’s said a few times she wasn’t sure she should be in a relationship, she’s focusing on herself. But what should I do? I do want a relationship and we had a talk about it and she said she pretty much just said she didn’t because she didn’t think I did want one? She says that she wants to focus on herself and then sends messages like this? I’m confused. I really do care about her but I’m not sure how to tell her without it sounding like too much or maybe I should just distance myself from her ? I’ve tried before but she got offended and asked why I never invite her to lunch, she asked why I don’t make an effort to talk to her like she talks to me all the time but in my head she’s told me a few times that she doesn’t want a relationship so I back off and then she doesn’t like that. Seems toxic maybe? I haven’t really had feelings like this for anyone in a long time especially another woman. I’m 22 and she’s 28. I’m not really sure where to go from here, she’s been so back and forth. So I know in my last post it seemed like I was the one who was pushing it but I’m definitely not. After the first time that she told me she wasn’t looking for a relationship I was obviously sad about it but backed off and let her have her space and was sure not to push it. It’s always “I like you a lot, but…” I feel weird because I think about her all the time and i try so hard not to because of what she’s said that she doesn’t want and then she messages me during the day about how beautiful I am and how good I look that day and showed me a funny post the other day from Facebook and said that it reminded her of me and said “I want a girlfriend like that” and then just looked at me.🤦🏽‍♀️
