Broken friendship? Is texting cheating?
*Zoe has been my best friend for about a year now, and she wasn't afraid to tell everyone. She is popular and has had more boyfriends than I can count... they never last too long. Her current boyfriend, *Josh, is one of my very close friends, and has been for about 3 years. He has always been sort of flirty towards me, we even dated briefly a few years back. When texting, he'll offer to stand up for me, carpool with me, and has asked me "who would you 'get it on with'?". Zoe found this out recently, and through a fit... though, I believe this is just how he is, and how he has always been. I text him a lot, but just today and yesterday, he's stopped being so responsive and has stopped texting back. Zoe, who has never been mad at me, has also mostly stopped texting me and when she does she seems rude. Zoe has accused me of having an affair with Josh, and trying to break them up. Josh is very kind to me still in person when she's not around, but that's all. She, when pressured by others, says she also isn't mad with me.
Should I end my friendship with Josh to keep my friendship with Zoe.. or, vice versa?
Does she have a reason to be mad? Is texting cheating?
Is what he texted me really that wrong and flirty?
Help please. All will be thanked.
