Forgive me, I’ve tried polyamory but I don’t quite know what counts as “cheating” when the relationship is opened like this.
So my sister (14) “Liz” went out with “Asher” (16) for like a week. Asher was always very giggly, flirty, and romantic with Liz and would find couple songs and say “That’s us!”. My sister seemed very happy with her new boyfriend.
Asher turned out to have a boyfriend he had been dating for a year before Liz. Liz knew about the boyfriend, but since he said “I’m poly and in an open relationship”, we all assumed the boyfriend was okay with it.
Turns out, he wasn’t okay with it and Asher got into a relationship with Liz before telling “BF”. Then, afterwards, he said “Well I like “BF” first and I like him better than you so I’m breaking up with you.”
Maybe I’m too upset because she’s my sister, but kind of a jerk move there on his end.
Trying to work out who cheated on who and who has more right to be offended in a relationship between a 14 and a 16 year old is not worth your time.
If it results in a basis of good values later in life, I’d say it’s definitely worth the time of OP.
However, it’s arguable whether making a post on Lemmy is the right way to get feedback on rights and wrongs, although I’m positively surprised by the comments here being so understanding and constructive.
It’s worth it if they are your sister and you care about them.
