Hold on, isn’t your perspective self defeating? The obvious reality of this relationship is that it is experimental in nature. If they’re informed of that going in then making mistakes is the best thing they could all be doing right now at this age where there are still fail-safes. Is it weird insofar as not being a norm that op is used to? Absolutely. Is it good for all of them to get this out of their systems and/or learn what their relationship types and preferences are? Also absolutely. Teenagers are gonna fool around. It’s what they do. The easiest thing for you to do is put aside your differences and respect their autonomy so that they can make their own mistakes while you still have THEIR respect.
Hope this helps, op. Being a parent will never be easy.
Not to mention people who wouldn’t vote for Donald Trump spouting this bullshit when all evidence directly calls out manipulation from Elon himself as well as Putin himself. Those two factors should be taking precedence in everyone who didn’t vote for Trump’s minds. Not this half baked “she didn’t try hard enough” bullshit.
