The first example isn't really her fault. If you got laid off it's either the employers fault or yours. On the others I feel you. Also it seems like you were too soft due to actually being a good, loving supportive partner, or got played and she kept you around so she could use you as a stepping stone to help her rise up, and now that she has hers she doesn't care about you as much anymore. Anyway this stuff is toxic and she needs to change or you need to probably detach and eventually cut it off.
