Would you reply if ur ex took a whole week to reply? why would she take so long?

my ex texted me last week how are you after 3 months no contact and I didn't respond for a week. (he broke up with me) I was going to ghost but realized Ill always wonder what he was going to text me.

we're texting now he's flirting and im flirting :/. He called me but I was busy. I think he will call me again. I'm confused about his intentions. Does he see me as a friends with benefits? Does he actually want me back?
