Oh and the grossest part, yes it gets worse, my sister is missing at least 7 pairs of panties....7, so I'm sure he took them?
I guess its his fantasy, but you've made it clear to him that you thought it was weird, and grossed you out. He should have respected that. But when he started stealing her panties,...I can't see things ever getting any better. You did the right thing. Find someone else, and move on.
Nothing gross about the panty stealing lol! Maybe he's attracted to your sister... I would say he definitely went over board with the whole kissing your sister shit, he should have had more respect for you than the fantasies in his head!
Thank you, I totally agree he should've been thinking about me and not her and us doing stuff, gesh! He did steal her panties, he had the balls to text her pictures of her panties at his place with an offer to "come and get them", so I think he was just into her and not me, pathetic, oh well he's not my problem anymore!
What a loser. You did right to dump him.
