There is a Swedish proverb that says shared joy is
a double joy and shared sorrow is half a sorrow.
Of course it is about being with a good companion.
Unfortunately, there are lots of cases of emotional,
financial, sexual or physical abuse against a partner;
but despite all, they stay in the relationship.
May be because they are afraid of being alone!
Those who cannot tolerate abuse are pushed
to build walls instead of building bridges.
