How Alex's relationship with Maggie started and ended does call Alex's sexuality into question.

It started when Maggie's previous girlfriend broke up with her, and when Alex asked to hang out with her, Maggie took that as a hint that Alex might be gay. Then Alex thought about it and figured she might be gay. Alex didn't know if she was gay before she met Maggie. But now, she wants to have kids. She had always wanted to be a Mom. She probably should have thought of that when considering a lesbian relationship.
