He's probably genuinely interested, but then I can also almost guarantee you that he laughs to others (including OW) that he can simply text you anytime, and you respond to him.
Sorry if that hurts, but that's why we all have to stop doing that kind of "needy/grabby" thing and emotionally detach. The idea is to make him see what he's going to miss, and to not be so available to him.
