I don’t doubt for a second that OP is telling the truth as she remembers it that she has been falsely accused. But I do stand by the fact that false or not - those accusations are why she has been estranged. She can choose to accept that or not but she has been told why. It’s that old saying there’s 3 sides to a story - mines, yours and the truth lies somewhere in the middle.
That’s the “truth” as far as the person estranging is concerned - that’s their truth, their recollection, their reason.
So to go back to the original “i don’t know what I did” - you do know, you just don’t accept it or think it’s a good enough reason. And that’s normal and rational, but from the other side - there’s no conspiracy, just because someone refuses to accept the reasons given or their validity doesn’t negate that those are in fact the reasons for the person who has had enough.
Getting stuck on “valid reasons” although I understand the need to justify the situation, is the issue. Who decides what’s valid? In a situation like this - it’s the person who walks away. It can be a big blow up, abuse, or like in my case over the daftest issue (yet again ignoring dietary issues for my son - giving him liquorice).
Example - I wholeheartedly believe that you insulted me, you’ve done it before and every time I see you I feel insulted. So I’m just not going to see you anymore.
You say, I’ve never insulted you, i have no idea what you mean - this is ridiculous.
These are feelings - you can’t tell me that you didn’t hurt my feelings because they’re my feelings. My truth here is that you’re nasty, your truth is that I’m a liar.
If I decide I’m done having my feelings hurt and cut you off that’s valid for me. You deny it happened so it’s not a valid reason for you - but you cannot deny you know the reason. You don’t agree, don’t accept but it doesn’t change the fact that I have explained from my perspective why I am done.
