If I were to move into a new partners home, I would compare what I would pay when living on my own, all expenses, and then pay about half of that amount, maybe more, but definitely not less, to my new partner. I would consider difference in earnings. A very rough calculation. I would not do anything sophisticated like listing itemised bills, or shared occupancy of rooms or whatever. That may be a wrong way of thinking, but that would feel right to me. The rest I would save, putting it into shares, whatever, that I could buy a place of my own in case things don't work out. How would that keep me off the property ladder? I could save more than with any other way of living?
My partner does not think like that. He thinks more along the line of what many of you argued for: what additional costs do I cause the household of my partner, let's pay for that and not more. He paid very little in the beginning.
I did not agree with that, and about a year ago I asked him for more, and he negotiated it down to the £700 he pays now, as a monthly lump sum. Because I thought I have to talk business with him, and I knew my line of argument above does not stand up to the way he thinks, I argued on basis of the shared expenses. £700 is really half of our monthly costs, including car and all, excluding mortgage. I found it awful in itself, and wrong wrong wrong that I had to ask him for contributing more and to have this discussion in the first place.
We went through a crisis after that discussion and I kicked him out, but we made up again after a few weeks, because he was distraught and had turned 380 degree and said that he wanted joint accounts, learn to cook, contribute to the admin, etc. I am now the one to be reluctant to have joint accounts. We get along well, he is a kind man, he is fun, we have a lot in common, he is lovely to my kids and to my mum, he just has a different opinion about finances. We have a happy home, where friends and neighbours are always welcome and gather around the kitchen table. My mum is an incredibly generous human being that enables me to have a fulfilling career, and she runs this household with energy, humour and warmheartedness, and no money in the world could reward her for what she is doing.
Am I a money greedy kind of monster because of how I see things? I am frankly stunned by some of your posts.
