If the relationship is toxic and you feel that you will be better off...then yes, that would be the way to go.
I have severed ties off and on over the years. I spent many years without any contact with my mother and there are only 2 reasons I have contact with her these days...
1. I have teenaged brothers (and one day they will be free of her also, so it won't always be an issue)
2. She is playing a very good game of hiding her true identity from her current husband, so she is more tolerable these days (that poor man!).
Our contact, however, is limited and truly, on our own terms. She is still very toxic, only we don't allow her to affect us in that way, anymore.
That said, she still makes our heads spin
I, however, do have this incredible ability to cut all ties and not look back. Things like that do not affect me. It takes me a very long time to get to the point of no return, but once there, I am DONE!
Only you will know what is best and I think you already have your answer.
Best wishes.
