She thinks his future should be with someone that matches his age with a better future prospects. She just want to be with him until he got tired of her and leave. That's probably why she don't want people to know about their relationship. Even if, ML cheats on her, she probably be okay with it. Thinking there is no future for them anyway. That's how deep her inferior complex goes.
