Oh dear Lord be careful of thinking that way.
People rarely do something because they're evil; there's always some reason behind bad behaviour that is not, in itself, bad. But at the same time they are not helping you or looking out for you, whatever they think. Tolerating such behaviour sends intirely the wrong message and confuses the hell out of you - always thinking why people do the things they do instead of seeing the effect it has on you.
You need to be really strong to pull this kind of thinking off. If you're not, make sure you respect your own hurt feelings more than others' intentions. Be careful.
In the end, just love is not enough.
Sorry for the glum warning; I wish you the best of luck. To answer your question, one or two friends knew because she told them, but they never noticed any more than maybe her sitting on the floor at my feet while watching TV. To me it has always been personal, no real need to share.
