I was born in Beaumont, TX.. and googled it. Though it was whacked pretty hard by hurricanes, there's no reports of swine flu cases.
Your spouse is making choices, trying different things all of which are out of your control. Losing her job is a consequence of her actions. It's odd.. I found, that in my case, pining away for my spouse during the divorce proceedings was a form of pursuing. Worrying, projecting concerns does nothing positive for you.
You can do whatever you want, be in whatever state that is right for you. You're not alone, you're a caring guy, you have lots of great qualities. Sometimes I think the best way to get a spouse back is if you're the one who leaves. If they want the relationship they move heaven and earth.. if not.. well, that says something.
As much as you're hurting.. it's not all about her.. it's about you, the choices you make, what you're willing to accept, what your boundaries are to stay healthy in your mind, body and spirit. Try forming a very simple statement of how you feel, where you're at... and compare it to where you want to be.
