Sooo Eve deleted my post and I couldn't read the replies

I wrote the post about my friend's relationship, her first cousin started taking to her when she was 15 and he was 21 (it's not illegal where I live) but I simply can't agree with it but she's totally nuts for him, they've been together for more than a year, she's 18 now. I just can't stand what a 21 year old could find in such a young and innocent girl and that they are literally FAMILY. She knows I don't like him, btw.

Any thoughts?

EDIT: YOU KNOW WHAT'S WORSE? when she started dating him I told her "be careful, he may just want you for sex" and she was like "Oh I know he doesn't because he's a virgin" 🙄🙄 Yeah right.
