Girls- why would the dumper want closure?

Anonymous
We dated for 2 years but left me for her current bf. They have been together for over a year and I have not seen or spoken to my ex in about 10 months. She didn't want to talk to me. Well 10 months later, she emails me out of the blue and ended up calling me. She said we can't talk after the phone call because she has a bf and it's not fair to him. She said it was a closure phone call. Why would she end up contacting me after all this time and tell me we can't talk after this phone call? Why would she need closure being the dumper and in a long term relationship with her current bf?
