No matter your age, if your parents did this... what would you do?

Imagine you were with your significant partner (as you are now, or were in the past) and your parents due to possessiveness issues, decided to keep all activities separate, what would you do?

For example, take you for an all day visit to other family at Xmas time, without your partner. Or, want you to visit, without your partner, or to chat to you without your partner. How would you deal with it? Plus, how would you as a partner deal with that?

There was no reason for the partner to be excluded except that they disliked the ‘idea’ that he had a partner, not for any personal reasons against the partner.

In other words your partner did not exist, or you as a partner did not exist.
No visits either way, no acknowledgement either way.

If your parents did this what would you do. If your partners parents did this, what would you do?
