If she is after hubby she is either stupid - to ignore you when she knows you're alone and not when he's home, or else she's playing you cuz she senses it may intimidate and divide you both - or it's all a coincidence!! - I've heard of some women doing this tricksy stuff like they're deeding you rope to hang yourself with - seems far fetched to me but somepeople are waay baad on messing others around like garbage.
Take T's advice for a quick resolution and find what's the deal!!
