I have a gf who I've been dating for about 6 weeks. Last night, we were talking and past relationships came up. She said the last serious relationship she had was over a year ago. The guy she was "serious with" wasn't serious with her. He apparently moved out of the area. But she said they are "still great friends" and keep in "regular contact" with each other.
Is this something to be concerned about? I wouldn't want to keep in regular contact with a serious ex unless I still had feelings for her.
