Indeed. I've seen this happen several times to friends of mine. In the case of one, his girlfriend cheated on him in a fit of pique, blaming him for not meeting the unreasonable demands to which she felt entitled. She had the idea that she could fly into fits of rage, and that would make him want to commit to taking her further into his life and cementing the relationship.
You'll note that "she could fly into fits of rage" and "make him want to commit..." place the blame where? On HIM. HE is at fault. HE is not paying enough attention to her, her needs and of course HER feeeeelings. In the wanton female hamster wheel brain, that adds up to HIS FAULT. She's not a slut; HE drove her into the arms of another man...cue the Gone with the Wind soundtrack...
Meantime, she's riding some better man's c**k, a man who "treats her well, listens to her, tunes into her issues and needs, and rubs her feet." Also, known as a bad boy / alpha / sport coat asshole. A potentially better / more exciting partner who "brings more to the table." See how that works? She cheats, and cheats "up" but it's all her current man's fault because "he isn't meeting her needs." Meantime he's working his ass off 60 hours a week at the office to make the mortgage and car payments.
And if caught, even by her own girlfriends, then well, "like, I dunno, it just happened." It's never her actual doing. "It just haaaaapened." If my BF/husband hadn't worked so late all those nights, then Markus wouldn't have had the opportunity to come over (and bend me over).
The only commitment that is in question is hers. As in her original commitment to the relationship. And flying into fits of rage? That just screams "crazy" to all men. Further pushing her away, but get this - it's still his fault because he thinks she's crazy, even if she isn't. See how that works?
Separate subject: as for massage and happy endings, not cheating unless your own spouse / sigoth can give a good deep tissue, cranio-sacral, and reflexology treatment ahead of sex or a righteous handjob. Oh, she can't (read: won't)? News flash: masseuses and masseurs will happily give a female client the same treatment. But in that case yet again, "it just happened..." and it certainly wouldn't be her fault.
