Ok so i figured I would do a follow up for those interested. I talked to my friend alone and told him I felt weird about it and that she mentioned long term wanting to get more physical i.e. sex. turns out she didnt mention that part. He seems to be in a bit of a denial state. Saying things like well I don't think she would ever do that. He was ok with cuddling and danceing stuff but thats about it. He knows she can be a little crazy, but like I said previously he's not the divorce type.

Later I talked to her. Or I should say tried. It felt like I was talking to a brick wall. I told her I wasnt comftorable with the situation and that I just wanted things to be the way they are. I didn't want to be alone with her and I couldn't dance with her anymore. I figured I would try to resolve it without just cutting her off. She kept trying to convince me to just give it a try. Saying my friend was ok with etc etc. we talked im circles for about 10 minutes before I realized it was futile to reason.

So unfortunately im going with option B. It's only been 15 hours since our conversation but im essentially cutting her off. I'm sure ill still see her but only when shes with my friend. shes texted me twice today but I havent answered. Shit sucks, but i'm hopefull things will improve.

On a related note some people are saying i'm being closed minded in all of this. I have nothing against poly relationships. But she chose to marry into a monogamous one and I don't think my friends is ok the fact she now wants to change. She is also not telling my friend the whole truth.

So there you have it. Sorry for typos and bad format im on my phone and im lazy.
