Well now my son and his girlfriend are fighting. I got a text message just saying "sorry but I'm leaving" from his girlfriend. They won't answer their phone or anything for me to get a clearer picture.

Why do they do that? Just to get me all worried?

I could only guess that the girlfriend wanted someone to tell that to, that would end up listening and not just brush it off. Alot of times we fight and sadly bring others into it (even when it is just a bicker fight, no biggie) only to "have someone" on our side, or just someone that we can vent to. That is probably the case. :)
