Could their relationship work in real life?
Don't get me wrong, I thought it was sweet and touching that Molly was willing to make the sacrifice of dealing with his memory because she had fallen in love with him. She at least was willing to try.
But could their relationship really last? I know they made Gus tell his friend that he loved Molly, but if every day was really as though you were meeting them for the first time, could you ever really experience the true sensation of love?
What if what he was feeling was just the typical stuff everyone feels when they meet someone really great, but if he actually didn't have his memory problem, he'd eventually realize that he and Molly aren't that good of a match, and it's just the fact that she's cute and pretty and nice that's making him say he loves her? Or is it possible for him to still feel love for her because he has his notes, and even though he can't remember it, he knows all the experiences they've been through and that she's been there for him through the years, etc.?
I guess it's irrelevant to Gus, because sadly, he never could experience love in the sense that the rest of us do, with his memory problems. But is it at all realistic that Molly would stay with him, when she's not even positive he would indeed love her if he got to know her the way a person without short-term amnesia could?
I guess it's not impossible, since some people stay in far unhealthier relationships. But maybe what I'm more curious about, then, is whether it's even realistic that Molly would say SHE had fallen in love with Gus, when she doesn't know the true nature of his feelings and doesn't really know the true him, either. As long as she may be in his life, he's still acting each day as though he's around someone he just met, and therefore not being his true self.
