They'd deserve each other...

Lol good luck

If I had no more feelings for the ex it wouldn't bother me at all and I'd wish them happiness. When I fall out if love, they can date my mothet or my brother. It's if there are still feelings it would maybe kinda hurt or piss off.

If brother, disappointed, cus he's got a very kind wife that was his highschool sweetheart

If sister, down right f***ing shocked, they're not at all into other girls...

I'd probably say "good luck with the headaches, pimp." .......... And maaaaaaaaybe something about used goods but, THAT'S ONLY IF SHE TRIES TO RUB IT IN FIRST!! ┴┬┴┤•ᴥ•ʔ🔪

I’d be horrified but I suspect she’d love to. What kind of sister supports the sisters ex in a break up!!

Not sure who would have the worst end of that deal.

Both of my sisters are straight! 🤣

Wonder why my siblings are cheating

Id tell them go for it

Ohhhh heyhul nooo.

I'd laugh . Poorthings

Eww just ewwww

What ex? 👀

Poor guy🤭

nothing... get away from that race if the sibling was elder.. if younger, see if advice is needed...

I’d laugh
