Oh my friend, I'm so sorry to hear this... I know how hard the past couple of years have been for you both but I also know how much you loved each other... wish I had some magic words to make it any easier but I haven't been given that gift... sending you huge love and virtual hugs until I can get them to you in person.
People will say she's in a better place. And you knew it was coming. Yet the moment still strikes red hot and burns deep. Bud, I'm am here when you need me. Not if, but when. Anytime. Love you both, Don.
I'm really sorry to hear this, you do have my sincere condolences.
If you want to converse with someone who's gone through a similar experience, please feel free to PM me. I don't know if it will help you at all, but the offer is there.
