Hey guys so basically I secured an FWB through tinder but she's on her period until around next week... it should be strictly business with this girl so how do you think I should keep her interested for the week so I don't fuck it up?

She's very attractive and the last time I tried to make plans, she ghosted until after. I think maybe she was with another tinder date. I know girls get a lot more options with online dating and I want to see this girl so what can/should I do to secure this?
