Hoping this can be saved, but having doubts

[reframe]

Thanks guys.

Part of what I'm really struggling with here is what appears to be somewhat conflicted advice between this forum and my coach, Chuck.
He'd advised me to "treat her like my sister" and continue to be friendly and supportive (i.e. help her move if I can keep upbeat during it) etc..

Before the revelation from her about OM yesterday, she was attempting to make plans with me and generally being pretty friendly.

While it hit me like a ton of bricks, I strongly suspected it was going on, and she said wanting to date was part of her motivation for moving out (See convo a few pages back). I'm honestly not even sure why confirmation of what I already was fairly sure of was so hard for me. But I found myself unable to sleep last night, thinking of her sleeping with OM.

Part of me feels like I should continue to do the non-pursuit "be her supportive friend' routine.

Part of me also feels like (as was said a few replies ago) that's complete beta male behavior.

I'm having a lot of trouble reconciling the two. I'm also wondering what the point is at this point. Even IF (And it's a big IF) she decides she messed up, I'm not sure how I could trust her again.

Feeling very lost and hopeless right now.
