Honestly, after reading this and your other topic, what this Louise girl did was absolutely inexcusable. When you two married, you vowed to remain side-by-side until the very end and always support each other, and then she suddenly turned around without warning and spitted in your face! She never mentioned how she was feeling about your marriage nor did she make any kind of effort to save it. She just selfishly said fuck it, and I'm glad you see this. But do realize that if she ever comes back (which sounds very doubtful), you cannot forgive her for this. In fact, next time you do talk to her, you really need to give her a big yelling for all this bullshit she's put you through. Not that it would do anything, but it's just horrible what she's done, and when I read about it, it leaves a sick feeling in my stomach. The least she could have done was give you some heads up about the way the marriage was going, or at the very least, at least agree to pay the rent, etc. for a month longer until you find a job.
But you know, you don't seem to respect yourself at all. If you want others like Louise to respect you, you need to treat yourself with the care and respect you deserve. You need to get up, face the situation, and overcome it. You need to become self-sufficient and be able to support yourself physically, mentally, emotionally, and financially. Otherwise things like what Louise did will occur. It's impossible to maintain a relationship of any kind if you do not respect the other, and it's tough to respect somebody if they do not respect themself.
You need to force yourself to eat, wake up, and do the things you always did before. You need to make it a point to move on with your life and tell Louise she can go fuck herself like the silly bitch she is. You just need to get back in control of your situation and life so you can feel good about it.
Best of luck.
