Does she have hidden mental issues?

Hi guys I'm facing An problem and honestly Im thinking and kinda wondering.
My ex I don't want to be her at all if she brings me a ton of gold I don't want her.
I honestly feel I'm dealing with the joker from the dark knight she asked me a favor then that favor turned to something else she didn't even said thank you instead she doesn't talk to me at all ! I asked her many times what's wrong with you but she smile coldly like I must pull you down she had severe trust issues and never believed anything that's why I did broke up with herI believe even if I slap her or pull her she will laugh and smile like the joker I feel she wants to prove I'm not right and my beliefs are not true I personally believe in loyalty and kindness and I'm faithful for family my job my friends generally Im just peaceful person but if someone cross my boundaries it's not fun anymore. Anyway though it's been 3 months since then I sometimes wondering if she has any kind of mental issue like something more than trust issues I had to block her on everything I feel she became scary with her cold smile I don't even want to ask why anymore walking away much better than involving with such person
Does she have hidden mental issues?
