<prompt> Human: Partner and I are making roughly the same amount of money. I was asked to move in, I asked how much my rent would be and was told to pay half the mortgage. We have been dating for a year and some months. We have been splitting everything from restaurants, groceries, movie tickets, vacations, cab rides... from the very first date. Everyone pays equally we literally 5050 on everything. I have no debt. Partner has student loan, car loan and the mortgage. All these loans predate me.So here is my problem. For me moving in to his apartment has several drawbacks. Right now, I have a large bedroom, I live with room mates and my living situation is totally ok. I live about a 40 min subway ride from my office one way. My rent right now is 830, and my transportation comes out around 140 a month.If I move in to my partners apartment my commute increases to an hour and 15 mins one way and my cost of transportation would jump up to a whopping 400. If I pay half the mortgage that was proposed my rent would be up around 1200. So over all, my expenses would increase with 600 monthly, my commute would be significantly less convenient extra time, extra money plus no subway that runs every 10 mins 24 hours a day but a train that runs hourly or so and all this for having essentially half a bed plus some closet space in the new apt.This seems like a really bad deal to me. This feels like the SO is getting a great deal literally cutting expenses in half on his end while I almost double mine and get not much in return. What are my options here? If I am paying half the mortgage should I receive equity? Doesnt that worth something that by moving in I forgo my own opportunity to buy something and pay my own mortgage, instead of giving away the money? I know there are tax benefits for the interest, should I receive some of that money when the tax return comes if I paid half?It is implied that one day ifwhen we get married this will be essentially ours. But if that ever happens all the car loan and student loan will be ours too which is a whole another story.I would be open to move in and maybe pay the same amount of money I am paying right now still would get hit with the extra transportation cost but paying half the mortgage does not seem reasonable to me given the whole scenario.Edit: Thank you all for the adviceopinions, I think for now I have the answers I was looking for. What I gathered is that overwhelmingly the opinion is that for me, financially, agreeing to go 5050 on the mortgage as rent is not a good decision. And yes, it makes sense to me now that I dont get any equity so that is that.Some people were wondering where we are or how is the mortgage so expensive vs my rent. We live in the NY area I live in Brooklyn, hence my easy commute to the city with the subway, he has the apt further out on the Metro North line, hence the travel expense increase 280 monthly pass for metro north and then you need a metro card to get around the city. He bought the apt before the market crashed so actually the mortgage right now is higher than what he could rent the apt for. I tried as much as possible not to bring anything realtionshippy into this. I was looking for advice on a purely financial basis. Thank you again for putting up with this and for the replies it wasis very helpful.  <response>: You are right, its not reasonable. If anything you should be paying less than you are because you are technically downgrading. I know that he is your boyfriend but its still a really shit deal. If he wants you to move in with him he needs to also compromise, not just you. You need to talk to him about it.
