It was actually a civil conflict so asking another countries/kingdoms king for help is equivalent to asking that king to take over the country/kingdom entirely. Unless they were fighting another country and were asking neighboring countries/kingdoms for assistance then sure they might help but like nah. Also if they were to actually ask cause they have relations between each other it would've been a no from the people of the princesses country. Why? Cause who tf would want to fight for someone else's motherlands internal conflict. Like. Why should my country sacrifice our people for other peoples problems. Unless we get benefits then fuck that. Plus they were just dating, not married. And if a country can't even support itself in this internal crisis then that's a fucking big ass embarrassment. Yeah love is great and all but just because affection is layer upon each other doent mean we have to ignore the bigger picture in this political view. If anything that duke was fucking smart for using this crisis as an upper hand to place his daughter on the throne. The prince just lacks common decency to fucking talk to the princesses of what had happened. He should have told her sooner rather than later. And she had to find out through an official announcement of marriage. Damn, I'm glad she dropped his ass.

I getchu, but they promised to get married when he settled the affairs in his kingdom. This dude was basically her fiancé already so he had an ally in her kingdom. She’s obviously the heir so he’s a soon to be co ruler of her kingdom. The country’s would end up being conjoined anyway, so he had a perfect ally. Even if my girl couldn’t officially send reinforcements she could secretly send aid and he chose to get support from a domestic duke. If mc was the villainess, this would be a major insult and it would result in a war. When he promised to marry her that’s a pledge of allegiance and he broke that shit. Besides the dudes country is barely out of a civil war. If girls dad wanted to take the kingdom by force he could do so fairly easily. He betrayed her, insulted her honor, and made her a laughingstock. Her countrymen would be pissed as well and again if she were a villainess war would happen so fast because the guy literally broke an alliance. I agree with you that the duke was smart but you can’t say that the prince had any common sense.
Hang on, so his gf was a princess in another country and he chose to get reinforcements from a Duke in his country? Why didn’t he just ask the Princesses country for reinforcements? His excuses are bullshit bro
