Polly route would be much better if she didn't just tell you she was cheating so upfront. I don't like willing cuckold stuff, and the binary of the decision makes it either that or breakup. I was hoping she'd start doing stuff with guys on "lonelyfans" (great name btw, funny and more honest than the real name!) and then that would cause more drama, but she just 'hey babe, i wanna keep sleeping with other guys will you be a nice cuck yes/no' and the path basically is over for me there.
Actually I think the problem with the route starts earlier with Anna telling you Polly is cheating. I think earlier decisions should affect whether or not Anna blabs on Polly or not. Like if you support Anna cheating on her own bf maybe she keeps it a secret idk. Anna coming out so early in the route with hard proof of Polly cheating kinda puts the thing on rails after that.
