They both suck as partners and I seriously wonder if these are just characters they play for the show. If Katie was my sister, Schwartzy and I would be having a very serious discussion on how he talks to her and all the cheating.
With that said, Katie sucks just as bad and they both seem to bring out the worst in each other and there simply seems to be no true love between them to want to treat them each other as if the other is the best thing to ever happen to them. It’s a toxic relationship for sure.
Lastly, to be pedantic, your post isn’t an example of begging the question. BTQ doesn’t mean “The question begs to be asked or The question that should be asked”
BTQ is used to indicate that someone has made a conclusion based on a premise that lacks support.
BTQ means by thinking that the argument raises a specific question--it begs the question--What's your support for that premise? OR more informally, What does that have to do with anything?
