How do you cope when you sense people are lying but won’t tell you the truth?

something went on between this girl i know and her co worker but no one there seems to want to talk about it , i would not of ever suspected they'd be involved as there not same age and don't seem to have anything in common other than work. perhaps it be best to just not know but it might provide some closure to know the truth , i get the sense someone there or all of them are lying to me
