Met a married milf last month, exchanged numbers after a short convo cuz I felt she was really into me the way she was staring at me while we were talking.

Texted her that night to just say "It was nice meeting you today".She replied in the same tone.

Tried being a bit funny by sending a one liner joke the next day but she kept me on read.

After a few days, texted again, she didn't respond.

After a few days, called out her flaky behaviour in a non needy way and she immediately responded with lot of apologies and how she was super busy a d missed my texts and even told me that she wants to meet me up for "coffee or lunch".
I told her I am ok with coffee and lunch doesn't interest me.

I was being non-needy (atleast thats what I think) and we worked out the logistics of the date.Notably, she insisted on a day date citing her weekend evening classes and I agreed for a day date.

I followed up a day before the date to confirm but she ghosted on me saying she is sick and down with the flu and she would love to meet me once she is well.
I didn't try to reschedule and I just said "Rest well".

After 4-5 days, I just asked her how she was and she has kept me on read ever since.

I didn't re-engage her cuz I didn't feel right.

Dear Men, I am requesting your thoughts/feelings on

• What does the girl's behavior says ?
• What went wrong with my approach ?
• Should I re-engage her and in what way ?
