For a whole lot of homeless people the answer is nothing. Nothing happened. They just slowly slid into homelessness as they were slowly priced out of society.
About a month ago I was at the gas station filling up my 24 year old clunker when a homeless guy came up and asked if I would give him enough money for a coffee. I was going to lie and say I didn't have cash on me, but it occurred to me that I'm one bad day from being in his shoes every moment, so I checked the emergency stash I kept in my car and on impulse just gave him the whole pile of it. Idk how much it was, not a ton, but a handful of ones and maybe a $5 or a $10. And yeah, a week ago, that bad day happened. My husband dumped me via text message, and now I'm very, very close to homelessness in the next few weeks or months if I can't find a place to go soon. It's not always drugs, or addiction, or laziness. Sometimes it's making what look like good decisions and just getting fucked over.
You don't have to make any bad decisions for some EggHead in Accounting to lay you off, or for you to find out you have cancer, Or for you to be hit by a run away driver leaving you unable to work.
The possibilities are literally endless and most of them are no one's fault but the system we live in.
Your husband not even having the guts to tell you in person is awful. I wish I could punch him in the throat. I know the universe isn't necessarily fair, but damn I hope that your little (and at the same time grand) act of kindness will somehow come back to you with positive karma or luck or whatever you want to call it. And I deeply wish you to find and maintain stability in your life soon - financially, mentally, and with better and more reliable and loving people in your life. Fuck that husband of yours.
That fucking sucks man. I can't even imagine leaving my partner like that. One time we had a short spat, and we STILL made sure she was atleast okay. I hope you find a way to be okay. This is also coming from someone currently living in a motel.
I too believe the youths are destroying our glorious language… look at the stately meme, reduced to this confusing image. We must start over with Esperanto! 
Reality is just a simulation that forms around you and the 'internet' is a big part of that, it takes way less effort to render everything into a small 2D square in your hands than if u look up.
Hey, don't undersell yourself. There's still time to try meth. You only need to do it once.
(Disclaimer: You should never ever ever try meth, even once. The euphoria is better and more addictive than masterbation. Just try to quit masturbating permanently - you'll have an easier time that trying to quit meth.)
