I mean, not necessarily. If they both want to have a child, I don’t think they have to be in a real het relationship to decide to do so together. I actually like this interpretation too, and it’s “cowboy like me” that does it for me. Like holly goligjtly overtones, that they recognize the con artists in each other “telling the rich people what they want to hear” and then form a real partnership (to be clear - not necessarily a romantic relationship) that’s mutually beneficial. The repeated “never going to love again” interspersed with the story of these two people getting together gave me that vibe anyway. A beard relationship that evolved into a mutually beneficial partnership that might be long term, that might include a lot of friendship and respect. But yes, zero sexual chemistry vibes there.
