If you are to use the Hexagram you provided, the answer is no.

she was the querent

That has been taken into account already. The answer is still no. Your friend was overreacting in short.

I told her she wasnt trusting him even though i didnt really know if he had a relationship with someone else It looked like he was a bit sensitive about her arguments rather having an affair
