I don't talk to my sister We just don't get along and last time I saw her she called me a thief in my own home.
So she sent a Christmas card,and I told my DH that I'll just bin it. He then went on that it was a shame for the children, that they have the right to know her, etc.
My 13yo has her number and she can reach out to her if she wants to. I don't see the point with the 3yo.
My DH could see that I was starting to get upset and that maybe I would appreciate never been called a thief or not having to listen to all the intimate of her relationship with my secondary school bully (who destroyed my self esteem for many years) rather than silly cards. So he said he understood and that was the end of it.
However I think he should accept that I simply don't want her in my life at all rather than feeling judged for my decisions.
