1.) I think by « available » Gillian meant emotionally and mentally. You know. As a person and a man. David has that and kindness so much. So, so much. 2.) I agree with the other anon. He isn’t just her only love, he’s her last love because they’re forever and together. 3.) And the « Schmoopie » thing was imo what it was meant to be. A public declaration of their relationship. There’s nothing to wonder about imo. Gillian was pretty clear!
