Why can't my ex-gf act normal a year later?

Broke up cause she was emotionally cheating.

I haven't contacted her in a few months.

She STILL ignores/blows off any form of contact. You'd think she'd be able to act reasonably friendly/normal now.

What do you think the reason is?
She's still hurt and when she sees me it hurts her.
She doesn't hurt at all and just doesn't want to talk.
She's still hurt and wants to move on.
Another option (please specifiy)

She actually started talking to me when she saw me two weeks ago, but is back to ignoring.
