yes, and things like that will continue to happen until you both find a way to communicate effectively in a way that is respectful and authentic for you both.

I think with therapy you will learn how to do that. I think if you work out with your therapist what you want from your relationship with your mom right now then that could help. MAybe the problem is in expectation. What do you and your mom want and expect from having a relationship with each other? Is that something each is willing to contribute to the other? Are there certain "flash" subjects that need to be respectively avoided for now.

If all your mom can cope with is surface level stuff, then could you accept that and work out the deeper hurt and pain in therapy? Can you work out in therapy or at least before talking to your mom bout this, what your boundaries are, how you want to conduct a relationship with her?
