if you take the red pill and fuck your friends mum
she will transform before your very eyes into a highly emotionally unstable and immature friends mum, trust me.
the 'are you mad at me' thing really struck me as something a 16 year old girl says to her boyfriend when he hasn't replied to a few of her text messages. an older lady should really know better. there is a good type of cougar, the sorta classy, discrete type; she ain't it pal. you will contract a serious case of STAGE 5 CLINGER ALERT which your young self really can't handle right now. this is why no men her own age will date her.
you'll also acquire a sick story to tell to your future buddies and brag about but honestly, it probably isn't worth all the drama and hassle. it will also more than likely make your relationship with your friend degrade when she turns full blown parasite on you and you avoid going there ever after (will happen, v quickly imo)
if you don't:
she will pursue you. hardcore. unless you make it clear to her you're not up for it and you think she's overstepping boundaries, she sounds like she is already in stage 2 cling mode. might hit 3 before she gets bored and finds someone else. won't take long. my advice is avoid her, sounds like bad news. bitches be crazy.
