Hey Karen,
One thing to keep in mind, and this is only from my own expierience, is that sometimes it takes a little time for some guys to feel 'comfortable' baring thier souls, or to be open about thier feelings. Especially if it is someone who is not like that and has never been used to someone actually wanting them to open up and caring about what is going on.
This takes time for some, and some more time than others....I myself have no problem expressing myself, but alot of men have like a 'wall' to keep behind. And sometimes it just takes time to break down that barrier. It just kinda happens.. But still at times, there is that moment that they dont say anything for fear that the wrong thing will come out or it will be hurtful because of thier mood. Of corse, it is better in that instance if they dont say anything at all, then to say hurtful things, but everyone deals w/ bad days differently. Usually after the initial crappiness of the day is gone, they will come around...
I know that does not make it any easier, especially if you tend to be an emotional person and open yourself. But, this too, will pass. (hate those cliches'). Hang in there...It just takes a little time!!!!

Best of luck to ya!

Christine
