This is a bit of an AIBU but last time I went there I was attacked by a pack of wolves so hoping to get more sane advice here.
Brief background - I have been with DP 5 years, for the last two years we have lived together in his home country, before that we lived in the UK but separately. I earn between 1/3 and 1/4 of what he earns in a month (dependent on bonuses etc) and i'm finding myself more and more resentful of how things are split. I pay 1/3 of the rent and household bills which is fine where the problem is with food bills. He expects me to pay 50% of all food and extras which would be fine if he was willing to work to my budget but he expects to eat to the standard he wants and me to pay half, I do all the cooking I could easily make food I can afford 50% of but it would involve sacrificing things like beef, expensive cheese, fancy coffee etc. He is unwilling to do this and believes because I only pay 1/3 of the rent and he funds extras such as meals out that I should be happy to pay 50% of the food.
Doing this means 100% of my wages each month go on food + rent, I have absolutely nothing left. I owe my parents about 2000 pound which was what it cost for me to relocate and although they are telling me just to pay it when I can I hate owing anybody money. DP is militant about budgeting he keeps track of every penny spent and says this is because he is saving to buy us a house etc. and that I should support this but honestly it drives me mad when once a month i'm presented with a list of everything that's been spent and expected to produce half of it. Often the half is more than I have earnt that month (freelance) so it gets filtered over to next month and slowly every month the debt to him is getting bigger.
The resentment is made worse by the fact my earning potential has been hugely sacrificed by moving here, it costs me about 1/5 of my wages to fund my visa and the fact I don't have a penny left over at the end of the month means a trip home to see friends and family is impossible. Pre-covid we had been planning a trip and it was made clear I would be paying for my own ticket despite it costing a months salary for me.
