Talks on financial issues are generally unpleasant in any situation. Let's not talk when these conversations have to be done with the partner, who may not be the spouse, as in such a situation it would be less embarrassing.
Let's go back to the question at the beginning: Is it ok to ask for debt to your partner?
Referring to surveys across foreign websites, some people think that such an action should not be a problem at all. Some of them show cases where "debt-issuing" has helped to get closer to each other.
Another part of the idea is that getting a debt to a partner shows some sort of downsizing and preferring to look for them in front of friends or family.
