Men generally don't hold grudges for very long. We forgive easier than women, so I'm not surprised that Wade forgives Zoe so easy and not vice versa. I also expect George to have forgiven and no longer angry with Zoe when HoD returns.

Men might screw up more often, but it take less to end up in the doghouse. Men are just more laidback and takes things less seriously. That is why I was happy that Wade in that scene was still upset. He was even upset when she came with her bouquet of apologies and she then made it up to him later until Lavon interupted them.
