Is it okay to talk to girl who rejected me after some time about feelings I had for her?

There was a girl who liked me for a long time. We kissed we went out but she ended it. We didn't talk after that for like three months. Now it is a year ago. She is now in relationship with my friend and we started talking and thngs are where they were before and we are friends.
