That is the person....

There is lot of "problems" in the world which has no solution.
I think I am trying to address one of them. But this is from my
presepective and things I observed and some psychological way.
This is going to be asexual and for both gender. The solution is
to understand whether a person is spendthrift. In the present
world we are in a situation were we have to make earnest
decisions to spend money and save for surviving.

Ok not too much of philosophy, lets enter into the context.
A man/woman who is looking for woman/man has to first make contact
with the person and then try to understand whether she is a rite
person with whom life can be partnered.
Find whether the person is a spendthrift or stingy. Both are going
to be an issue. The person should spend reasonably and sometimes be
spendthrift and stingy. Categorise when and where a person should be
spending money in different ways of your choice. Since the person is
going to partner you it is your choice. Lead the person to the places
and find out how the person spends in places and how the person is
reacting when you are going to spend money.
Yeah I can see the obvious question that what is the inference from this.
From the way the person spends you can understand whether the person is
suiting your choice and syncing your decisions. Don't expect 100%, 75% is
far more better. Ok now if the person is matching you decisions then we
have to find whether the person is caring us or not/interested in us or not.

This is going to be bit complicated, but you have to be sharp while identifiying.
When you are spending as spendthrift or stingy the person should correct you
righteously. Note how much rights the person takes in correcting you and in the
case of others. This will give you an idea of how the person is considering you.
This will prove how much the person matches you and how much the person is
considering you and respects you. But this doesn't mean the person loves you.
But this is a step for proposing someone. The only thing in world which can
solve the riddle in world whether a person loves someone is just feeling it
and proposing it directly.

The pschological inference behind is very simple: we want to know how much of our identity, ego and superego is present inside our partner. Sigmund Freud considers human mind as iceberg it needs separate post to explain it.
