Molly was wrong. Just because we're in a weird place in our relationship, You want me to fail? That's fucked up.
If Molly's reason for not helping Issa was to set boundaries, then Issa wasn't wrong for not involving her. Hell, it didn't even seem like Issa and Andrew talked. It was Nate that kinda put it in motion. Molly didn't have any involvement, so why is she mad?
