I get that feeling, it's like a combination of pity and disgust. I mean, despite all her shit talking and waving her ass around (figuratively and literally apparently) May hasn't done anything objectionable that we have concrete evidence for. She talked a bunch of loli shit, but then suddenly wants to be a trad wife, so I'm inclined to believe she's just larping based on which guy she's with. On the other hand, like you said, she had everyone and their brother warning her that Ralph is the toxic pig we have all been saying he is.
With Faith, I could kind of get it cause 18 y/o going on a "fuck you dad" rebellious trip, but May is a grown woman, she should know better.
