I told her I wasn't going to see her when I come home and she said she was on the verge of suicide
Worry about yourself. I thought YOU were suicidal when you wrote the OP.
Here's the thing: You were low-hanging fruit. She was low-hanging fruit. You both picked each other and partook in the trick and the treat game.
Everything has pretty much been covered by everyone else. You have a void though. She can't fill that void. If I recall from the other thread she doesn't have much to offer you besides her vagina. I'm going to point you to this thread about what "LOVE" really is since no one has helped you to that information.
You've been away working hard, and part of your problem could be that you have some gaps in your foundation because you dove right in. You really want to read The Kidd's Definition of love:

Basically you are or WERE in love with a stupid, lazy, broke, slutty, bitchy woman. Her character ain't to great man. It's not going to be. You said yourself that she told you she was molested. Most of those women, coming from personal experience, have pretty rotten cores and are hyper-sexual. They typically suffer from narcissistic and bi-polar thought processes while being prone to exaggerate things in their head (sorry I don't know the psychological term for mental exaggeration).
That's fine because you can do something about that with self-control. Most women in society are stupid, lazy, broke, slutty, and bitchy because they feel entitled from what society tells them....men and women. Chances are that you will have the same problem right now with a woman with some practical intelligence, initiative, and drive, wealthy or not.
You just need to know the difference between the two women so that you know who is good for a relationship and who is good for a fuck 1)
You need to have a rough map of how your mind MAY be working and how society operates so that you can explore your triggers ....hence the links 2)
Then you need to find a path that you want to take 3)
