Julia,
At 5 years out (almost to the day), I don't drop by here often any more, but felt compelled to visit tonight and saw your post.
I also lost my husband to cardiac arrest, also in Colorado, also a common law marriage, a month or so after his mother had a stroke. I am so very sorry for all you are going through right now.
Sending you much love and a hug. And if I were still in Colorado I would take you to coffee and give you that hug in person and listen to you tell me about how amazing Chris was (and hopefully somewhere still is).
