Why the relationships then?

I often wonder why people make relationships.

I hear people saying that

No one stays with you forever,

That no one can wipe your tears

No one will help you when you need them

Everyone has to carry themselves

I do agree with what they say, but.

If what they say is true

If no one is going to be

There for us when we need them

When no one will be our support

When people are going to change, to betray us

Then why are these relationships for?

Why is there family, friends, love, are these just terms?

Why there are feelings, emotions, attachments?

I often wonder why people make relationships.. why? :')
