She said 'I love the validation, not you'. what am I supposed to do?

So we were onn and off for 10 years. I was the first to chase her as a 17 year old and she rejected. When she came back 4 years later, I treated her poor. So she moved away. Now I got in touch with her asking if she was single. she said she wanted to know me but told her 'I am emotionally unavailable'. She told me she is also emotionally unavailable but want to know where it leads to since there is pressure to get married. I knew by then, she was cold and definitely avoidant.

Now we work together and I tried talking to her after being ignored by her a lot. She said 'I miss you a lot. but the minute you give me validation, Im out. and when you are away, I miss you a lot. I miss you but at the same time I want my space'

I dont know what to do.
