How hard is it to develop a thriving relationship with your parents?

Very hard for me, for years my mom kept me away from my dad and all she did was tell me lies. I never got the chance to meet him,, and when I did finally meet his family he had already died. I don't trust her, and it’s hard to have a relationship with someone you don't trust. I learned to love my mom from a distance because that's the way it has to be for my sanity. But, idk your situation with your mom, I hope you're able the work things out, if not I understand.
