Is this weird from my Exes sister?

Me and my exes sister use to be real close. Once me and him broke up his sister still wanted to be friends. The break up wasn’t messy, it just happened. At first she’d occasionally FaceTime me and text me about her life. We never spoke on the breakup or anything. She’d ask me about my love life and suggests she helps me find ‘a new boyfriend’. Is that weird, knowing I use to be in a long term relationship with her brother?
