I assumed in the grand scheme of things of detaching or GAL, it's important for her to think I'm not fazed by all this.
WRONG. Detaching doesn't mean "don'tgiveachit." Detaching means that you don't base your OWN decisions on how SHE is going to react to it (there's more to it than that, but that's the gist of it).
What you want HER to think is "Badcompany is a man of honor, and it's obvious that he still loves me, but he does NOT agree with what I'm doing, and he seems to be moving on without me. I hope it's not too late to try to get him back once I figure out w.t.h. it is I want to do!!!!"
And I'm sorry too, but yeah, she's using you like a woman would use a gay friend.
