When and if your wife hurts herself it's a good idea to at least pretend like your concerned (even if your not) for her injury and her feelings regarding it. You don't have to cry with her or really do much at all except act like you care. Telling her she is overreacting or to "get over it" or that she's "not gonna die" really isn't being very supportive. Maybe saying something along the lines of "I'm sorry your hurting sweetie" or just anything that expresses that you do (even if it's fake) care.
I'm totally sorry if us chicks find it hard to 'take it like a man' or 'suck it up' like those of you with penises but that's just the way we are. Maybe it really DOES hurt and we just need for someone to care. We (or at least I do) do care when something happens to you and we really only want the same in return.
The only thing that hurts more than the injury is the thought that the person who supposedly loves up more than anyone else could care less. Well just a thought.
