Un-noted are numerous abusive scenarios...

Of lesser significance, but nevertheless continual..

Olga attempts to minimise any joint (mother & father together with child) activity.

If she is going for a walk with Dunia, and I mention joining, she states there is no need for 2.

If she is going and her mother is going, and I mention joining, she states there is no need for 3.

If she is going and her mother and her sister are going too, and I mention joining, she states there is no need for 4.

...Etc.

When at the playground today, and with Dunia joyfully interacting with me, she complained that (1) I communicate too much with Dunia, instead of just letting her play alone and (2) that there was no need for her to be present... and then she went home.

Re (1), it's totally acceptable that her father is completely talkative and interactive when near to Dunia.. Ditto re her mother..

The attempts to push me away are less and less subtle.

The jealousy and other spiteful emotions left unchecked are on track to damage Dunia.

Let's hope there's some 'check'
