Writing Believable Love Triangles

I don't know how helpful exactly this will be but I do have a romance and pseudo-love triangle (the MC isn't really interested in both girls) at the center of my last completed novel. The MC is a prince who is already engaged through arranged marriage to an earl's daughter who he finds boring, but falls for a foreign diplomat who challenges the champions of his nation to duels to settle disputes between their lands and kicks all their butts. So there's a double conflict for the MC in that he loves the foreign girl but is obligated to marry the fiancee who insists she loves him and they should be together, and the foreigner is also considered an 'enemy' by many of his countrymen. They wind up dueling and he runs her through with a sword, but she still beats him before saving his kingdom by pleading for mercy from her liege and then fights the main antagonist, a centuries-old dark elf sorcerer. She ends up going back to her country after deciding her career as a diplomat (and beastly champion of champions lol) is too important for her to abandon and he decides to give the arranged marriage fiancee a chance, having found out she isn't bad as he once thought. I might change it to an HEA with the foreign girl so I can label it a romance though...

 

Now that I think about it...

I do have several characters in political marriages. A couple are content with this; at their social level in this society, it's the norm. Politics, not love, determines ones spouse. But...

Tia, a central character in my 'Empire' series has a sort of 'list' of prospective candidates for her political marriage, and while she's resigned to this, she does have another romantic interest.

Likewise, Bao, daughter of a minor provincial governor in 'Labyrinth: Seed' had her heart set on marrying Amentep, a bottom rank aristocrat. Then she was rather abruptly informed she was be married off to a minor scion of the very powerful and widely despised Maximus clan. As far as she is concerned, this marriage will make her a social outcaste.

 

We relate to different people in different ways, and different sides of us come out in different relationships. I think that the Twilight series was a deliverable exercise in seeing how two totally different relationships could work with Bella and why people root for the two different teams.

One relationship promised mystery sense of the exotic, and another promised warmth and courage. Both are desirable. Perhaps the key is finding out what it is about each relationship that would make it stand on its own. Like some of the other commenters have said, I also dislike it when there is passivity in the girl, and the guys are jockeying about as to her decision was a winner-take-all, as opposed to a decisive choice for a particular person.

I'm sorry but to me love triangles NEVER make sense unless:
Boy 1 like girls and she likes him. Boy 2 likes girl but she doesn't know or play with his emotions of have that 'hmm do I like him better or the other one?"
Because when it's a 'which one do I like better?" I always feel she can't be serous about either because if she was she wouldn't need to ask herself. She'd just know.

I don't like love triangles. It's always obvious who she'll end up with so why have the second guy?
