Vinteagenanna, I was heartbroken reading your story.
I think everyone has their own 'take' on what has happened in the past, and sometimes you refuse to change your opinion because you know you are not a liar, and perhaps your children were influenced by their father, but being like that creates a 'stalemate'
Where does your mother stand in all of this? Surely she has seen what happened and will support you, or is she a part of the problem that exists now?
My heart goes out to you. I understand what rejection does to a person. It makes them feel as if they are unimportant, and self esteem is low at all times.
I think you have to look outside of the box you are in and try to look at this from another angle.
Don't let anything said turn into a confrontation. Keep your counsel and don't ask anything.
You were hurt because she snubbed you and she would know that, so in asking about it you have played right into her hands.
Remember, your children are always your children and even as grown ups they still play childish tit for tat games with their parents.
You are the adult here. If this were a game of poker, and you had a bad hand I suggest the good use of a 'poker face'
Don't let them win. Raise your head up and stop asking questions for one thing. One thing you could do is offer to help whenever the situation arises, and if you are met with abuse, don't play into their hands by getting upset.
I honestly can't think of anything else, except to say make a positive out of a lot of negativity.
Bless you x
