LionGuy, the same thing happened to me with an ex of mine.....we'd been together five years, and broke up mutually (although it was painful). He told me that he just needed time alone, to be with his friends and be a no-strings-attached kinda guy. Then I found out only two months later he was dating a girl from work. It killed me. But guess what?.......you get over it in time.
As for girls checking out of a relationship emotionally long before they actually end it.....I'd have to say Hayward's pretty bang on with this one. I think girls like to take time to get it all right in their own mind before they pass the news onto you. And since they've had plenty of time to make up their mind on how things are going to be, youre not going to change it. I admit it's a bit cruel.
