My bf's alleged kiss with his sister-in-law's sister...?

Sounds to me like H and K have something going on. Maybe its innocent for now, but they are flirting! Is that ok with you? Shes his sister in laws sister! He doesnt even need to associate with her unless its hi and bye. Just because she has a bf doesnt take her off the field. Girls and guys could care less. Dont let H play you for a fool. It may start out innocent but turn into something else. I say you nip that **** in the bud. Give him an ultimatum.... friends with her or this pussy. Seriously wtf... I'll be damned if my bf even texts a *****! lmao need to check his *** because gthey obviously have some chemistry....
