i feel like that's perfect? i see leon as having always been very ambivalent about anything longterm as well until he got all swept up, and i think that really feeds in well to an amicable split because once it all wore off and they stopped trying to force things to work it wouldn't have been a placing blame situation. it would have just been both of them realizing that the whole marriage thing wasn't for them in the first place and that's okay, so they were able to stay friends and still see the good things in each other that they fell for even though the romantic feelings are gone
