So I am in a weird situation. Would you guys handle this differently or what is your advice?

Basically, me and my boyfriend have been together for a year and a half. Short amount of time. We have lived together for about a year, have three dogs, all that jazz. Now, my boyfriend just bought a house in his name, as a flip. Which he wants to live in and fix up for a minimum of one year maximum of three years before putting back on the market. Anyway, my rent right now is $500. With the new mortgage, my rent would be $750 if we split the payment, on top of my other bills and expenses.

My boyfriend makes very good money. I only make $2000 a month. That new payment would be almost half my monthly income. Is it unreasonable for me to explain that because we are not engaged/married and the house isn’t in my name at all, that I would prefer to stick to my current rental amount on top of my other contributions to other bills?

I feel like if we were more serious, I would love to pay half. Anyway, is that unreasonable? I mean, I also pay for all food, half a phone bill, the internet bill, half gas/electric, and dog food. On top of financial contributions, my boyfriend does not have to clean or cook. I do all the laundry, cooking, and cleaning. He comes home and plays video games for 5+ hours then goes to bed. Am I being unreasonable? I want to mention that if we Were more serious, I would be more inclined to help pay a mortgage. (I know that I can move on my own, however, he asked me to stay with him.) I do want to move forward, so I would like to be able to hint that as well, I am not rushing to get married but I also want him to know that’s where I am at.

What do y’all think of that??
