" I wants to make her happy.

What more can I do? I think you may talk with and give her advice. She doesn't see the reality of life. She has very strong brain but not smart and specialy now when Ukraine is in war which will not know how long but not next year. She must learn to not loose people who can get sometimes support on these difficult times. We can remain as friends but not obligations for support.

Happiness is not about complex logarithms of the world! Happiness is simple postulates...
love every day
Love every minute
Treasure those who are near
Appreciate every moment.
And just live!
  To live... not to exist.".
