Correct if we assume that it's really Frank.

If you're Frank: Luna's right, but I think 
you're a cute friend that Amy's lost there. 
Personally, if I got into a fight with a friend 
which'd end in "divorce", I'd probably mourn a 
bit and drop it to go look for new people. You 
however do everything (contraproductive though) 
to get that person's attention back and to let 
her know how attached you actually are to her. 

I'll make a  - very rude - comparison: I didn't 
give my dog any attention except scolding. I 
left him all alone for 10 hours a day. There was 
no love, nor friendship I felt. To get my 
attention, he shit in my bed. And harvested a 
buttkick. Every evening the same. That poor 
animal begged me for attention and to love him 
back, but in a fashion that he only harvested 
MORE anger from me. I ended up kicking him out 
for the sake of all involved.

You're doing the same. And just like me who'd 
have appreciated that dimwitted mutt to show his 
love and deserving thereof by perfect obedience, 
Amy would probably prefer you crawling to her 
doormat with a bouquet of flowers and a swollen-
up-with-tears face instead of embarrassing her 
more and more on this public board.

Think about it. My comparison to a stinking shit-
eating greasy flea-bag may be harsh, but my 
advice is meant to help your goal of regaining 
her friendship. My point is however: the goal 
does not always justify the means, and even if 
it does, the means you employ can will 
get you into deep shit.
