I find it incredible how after doing more for her than any of her exs ever have that I am still the bad guy. I forgot to mention that she has also kept the family car which I paid £11000 towards.
I think this is just another twisted defense mechanism their illness taps into to make it easier for them to leave with less shame and guilt. They paint you black because they feel stressed, guilty/shamed, etc. and once you are black they can proceed with leaving guilt-free. It doesn't matter how much you do for them. Once they feel threatened the feeling overwhelms all logic. They do not act rationally, but from a whirlwind of conflicting emotions. It is part of their illness. It doesn't ever change, it doesn't get better.
