He's much too stupid to be a legitimate romantic interest. The author'd either be shooting themselves in the foot, or forcing an unrealistic character change, if they were to pursue that.
As the comments here may have indicated (and let me add a quick +1 to them, here) noone really expects the imbecile to actually behave in any reasonable way. Let's just hope she moves on to a divorce, and does so in a manner wherein she can take an advantage out of the relationship (be it by demanding repayment from the buffon, or gaining prestige, or whatnot) rather than the whole thing just being a waste (well, other than for the people of the dolt's territory, but that just ends up benefitting him in the end, so eh).
