that’s not really the issue for me. i’ve said before: it doesn’t make sense to sacrifice bughead for f*lice
my biggest problem is that it’s a shitty thing to do to your children. it puts betty and jughead in an awkward and weird situation. there’s no way other characters wont make jokes about their parents dating and if it’s incest, which undoubtedly will be uncomfortable for them, even if they know they aren’t doing anything wrong… which, that right there rubs me the wrong way, too. betty and jughead feeling like they’re the ones doing something taboo when they started dating first and then their parents got together. you can’t drag in the f*lice dated in high school argument here because a) it was 20+ years ago/they went on to marry other people and b) betty and jughead had no idea their parents had history
betty and jughead didn’t knowingly put their parents in a weird position when they got together, but, even if they had, they’re the kids. kids are supposed to be the more selfish ones in the child-parent dynamic. in bughead’s case, they definitely aren’t. fp and alice have repeatedly made their kids lives harder and treated them poorly. it makes them dating/fucking/whatever while betty and jughead are dating an in character move, but all the more worse, in my opinion. it makes you wonder if they care about their children’s feelings or quality of life at all. i don’t think we’ve seen much evidence that they do
