True story: I knew a guy who arrived home to find that his wife had taken their mobile home (which was parked on his parents' land) and moved it to an undisclosed location. Come to think of it, he didn't find it humorous.
I think girlfriends/boyfriends should be honest enough to leave when that's what they want but sensitive enough to mitigate the hurt and humiliation of the other person.
When people are married it is a whole different thing from boyfriend/girlfriend relationships.
Wait, what? (I guess I should have noticed something was wrong with your hijab.) So if you're not really a . . . hey, that means you and I can now get back together!
