Can't tell you how you should or should not feel. I know that for myself, the more I react negatively to things I have no control over, the less I feel good.
As a father of 2 son's, who's previous wife has worked so hard at poisoning their thoughts towards their father, that they want nothing to do with him ... for the last 22 years. I haven't seen them since they were 5 and 3, because of her lies and half trues. Now they're 27 and 25, and I think I can say for certain, that of course, feeling hurt is definitely allowed, but unless you accept what you can't change, then you are the only one that will be hurt long term.
My thoughts, let her know how you feel, but accept and move on. She's with you most other days. Take what you have
