How did you resolve disagreements with your partner?

SHE rich heiress, HE unsuccessful artist

It could actually be a well-functioning arrangement if the financier trusts the artist and he turns a house construction into a masterpiece (let's assume he has artistic talent, she less so).
He has no money, but surely, to make the place look cool, she pays him with her money and – above all – trusts his talent!

That's how a perfect match is made!

That’s how you get the right fit!

No no, unsuccessful artist who only has visions but doesn’t get anything done. Who plans a mural for years and sits motionless in front of the white wall for so long, but already keeps buying new materials worth several thousand euros.

I was talking about talent!

It is not about who gives up which job in favor of raising the children, but rather that the person thereby simply has a share in the other’s income.

Anyone who says soooooo much like that really doesn’t deserve anything else.... You are so great... yes, you are!
Character often shows itself between the lines

Dear Yvonne, it has long been clear not only to me that you are the best person character-wise here in the forum, of course in the perfect relationship and always doing everything right.

It only underlines my statement that she is building the house for herself, which is okay given the circumstances. The partner is just an accessory to not be alone, also completely legitimate.

Will he pay rent in the future or does he have to work off the rent?

You can choose.

Very judgmental, just the use of the term "Gutmensch" is telling.
Anyone who throws around polemics, artificially simplifies facts, maybe shouldn’t take everything so personally in the end and especially not come up with such exciting scenarios.

Who exactly used "Gutmensch" here?

I generally don’t take anything personally in a forum. Why should I?! You are all very kind and nice people.

I have to say, with us the discussions are limited; we really haven't had any real arguments yet. We complement each other quite well when it comes to the topic of house building. My better half is interested in the technology, for example, and I am more into the style of the furnishings and all the fine details. We coordinate, say what is important to us, and so far everything has been running smoothly. Of course, there are days when after hours of selecting materials, you're just exhausted, or even in a bad mood. But I think that happens to everyone sometimes. Building a house is simply exhausting; you must not underestimate that.
