We've been seeing each other for 5 months, we have a good amount of fun, bought each other Christmas gifts, we get along fairly well, but in my head I know I never want to date her seriously. We've never been exclusive and I've been seeing other girls the whole time, but she was only seeing me. I never really expect a situationship to last more than 6 months anyway. What would you do: time to let her go, discuss the new development, or just keep it going till the clock runs out?
