Uh why would it be weird? Because they had a good relationship? There's nothing weird being friends with your ex boyfriends other loves. It's not like I didn't have a good relationship with him either. Plus I saw that she wasn't feeling or doing well and I wanted to help her out. Give her advice, there's nothing wrong with helping someone out. I'm always down to make new friends and cheer someone up. So no it's not weird at all.
