Imdi99: Your H is being a dufus. Keep being strong and keep trying to GAL. Believe me, I know that is hard since I am trying to do so myself, but I completely feel your pain in everything you say...

I don't know if any of this makes you feel better, but you are not alone. Keep the hope - some days it is all you have...
