Cola is mad at me!!

Im not sure what to do...
Tango was spayed last week and I had to separate Cola and Tango as Cola was treating her as if it was day one all over again, hissing, spitting, swiping, ect.
I separated them and only allowed supervised visits so Cola wouldn't hurt Tango. They are fine again, back to being best friends....

Here is my problem, Cola was pulling the same thing on ME!! And she hasn't let up! I can't go near her
She always has slept with me, cuddled, ect except when I brought Tango home... though that time, she only went after me if Tango was there...
This time, I feel like I have lost my cat, I have no idea what to do~
Can anyone help?

PS Feliway DOESNT help!

Have you tried luring Cola with a treat, then petting and talking to her when she approaches? Maybe you have to make friends or she may be hurting in some way.
