Yes, my lovely, that absolutely makes sense. I've moved on from many people in my life - and some have moved on from me. I think of it as an energy thing - as we grow and change and move through life, our vibrational frequency changes and we just don't resonate or align with certain people anymore. Sometimes it's a gradual drifting, other times there's an incident - such as this one - that makes it abundantly clear that you're not on the same wavelength.
And especially when it's something as basic as issues of disrespect or other things that go against our own values. There's nothing saying we have to stay connected to those people - even when they're family.
I've had to cut off very close family members and it's not easy, but it was self-preservation. Life is too precious to waste it on relationships that are hurtful or destructive.
Not that you need my support or backing for your decision, but you have them anyway. I would do the same thing in your shoes. Sending you big hugs as you move into another phase. 💜
