You are totally fine.
I love that! Yvette is a firecracker as it is. She would hate his flirty ways and totally call him out about it. She has the tendency to love hard too, so regardless of how long it goes he'd always have a big part of her heart. I'd love it if he was her first also? Which makes it harder for her to fully let go. She does smoke weed too, so could be how they first met? We can totally play out seeing each other again after a while and see if it fits if it doesn't then I fully understand.
