Let's see ...
Meko: I'm really going to miss her company and miss talking to her.
Meko's Friend: Been crying every night and she can't concentrate on anything.
Whose feelings should count for more?
I'm assuming (maybe wrongly) that you want to do the decent thing ... you lost a friend, she lost someone she loves. No contest. Pardon her for screwing up your friendship, you'll get over it.
Stay the F*K out of her life! Period. You have nothing to offer to her.
