So guys - what do you usually answer if you ask a girl if she got time tonight and she talks her way out?

Asked a former affair of mine on Thursday (we still work together) if she’s interested to chill tonight and she didn’t really commit but said she gotta see on Saturday.

So I didn’t pursue it anymore waited 2 days without any comment on that and just send her a plain text today, if she’s up to hang out.

Now she said that she’s not feeling well and will tell me later if that changes - what’s a good reply to that? No contact would most likely make her think I’m mad at her but I’m open to any suggestions.

Just to be clear, I do have other options for tonight!

EDIT:

For anyone who's interested: Told her to get well soon after few hours and that I'm going out. First thing in the morning, she texted me asking what I did last night. Didn't even acknowledge that and asked her if she's feeling better. Gonna ice her til tomorrow - after all shes a co-worker and I'll see how sick she really is tomorrow.
