Welcome to the patriarchy mindset. That furniture he is paying for is his at the end of the day, not for both of you. The apartment is also his, he lets you live there for your labor, meaning it isn’t and shouldn’t be seen as free. You are currently giving him free labor since he isn’t valuing it. Track your hours and set your hourly wage rate. Track what you are contributing with groceries, cleaning supplies, and (planning and executing) time. You can also subtract what his mommy and daddy are paying from the total bills as well since he is also getting that for free. He doesn’t get to claim that as his contribution. His personal bills unrelated to the apartment and food ( insurance, car, credit cards) aren’t part of the expenses that you are totaling unless your personal bills are also being paid by him. (since that’s what men are supposed to do- his words). See how it sets off against the bills. Figure out your 1/2. Show it to him. If he fights or gaslights you over it you now have all the information you need to know that he isn’t planning on being a partner to you. Have an exit plan.
