I'm confused...you say you want closure but I read you want him to tell you he wants to try again. So which is it?
You're the Libra that is indecisive, he's not. If he wanted to try again, I'm sure it would have happened before 5 months. Stop over thinking and looking for hope and move on, after 5 months you should be able to without looking back...then again you are Libra and we do think that we leave a burning impression that makes us unforgettable ...well we can live in fairy land, that's our prerogative!
