Search Results: ex ignoring me

I went out on a friendly date with a co-worker in the building, but we don't work together.
It was fine, but she had me meet her parents, and that was awkward, but she said she wanted to do it again.
She never responded to me asking her out, and just ignored the question, so I gave up. I met someone else not long after, and the coworker started a casual thing with her ex.
Lately she's been acting like when we first started talking, and will flirt one day and avoid me the next. She's making it uncomfortable. People here, and my friends suspect she still likes me and either wants to try again or just get attention.

I dint care anymore, but her friend says she's bad at communicating, and doesn't know what she wants. Will she eventually leave me alone?

I had a relationship 4 years that lasted for a few months. It was the only relationship I ever had. It culminated in us watching a movie together in my bed, cuddling and kissing during the night together. She broke up with me the next day, saying that she would rather focus on her career than a relationship. We were both premed. We were really into each other, but she started to ignore me even though I just tried to keep our friendship going. I haven't talked to her since mid 2017. I think about her sometimes and wonder if I should send her a text just asking how she is doing. Thoughts?
