Particles that needs Company

Its the quarks they can never be alone. Reason is if they try to part
they get pulled back. They are confined to the horizon of the nucleus.
Never to roam outside its territory.. Why did mother nature show us
this feature was so important? Why split the EM + force into thirds?
How do gluons create this amazing feature that attraction(pull gets
stronger with distance?) Why don't quarks use +,and - and + and
-,and + and - to stick together?? bert
