I'd say "All good, feel better. When you're up to meeting, let me know." Then I'd move on and focus on other women. Reach out again in 5 days or so, and if she's not hard-yes for a date, then I'd delete.
What could i have done better?
Nothing . You don't second guess yourself just because 1 woman is sick or loses interest. Operating from a place of fear or holding onto past experiences will make you less attractive. Operate from a place of confidence.
