I’m surprised nobody else has brought this up yet, but how are you at making big decisions? Do you wait a long time to make them and then regret them? Do you make them early/quickly and end up modifying them later? Do you set up pro-con lists, and how much do you fall for new friends/life experiences/food/a religion/a new house/etc? How many nights do you spend at each other’s places - and where are you more comfortable? Why? Have you seen him clip his toenails? Are you or he a slob, the other a neatfreak? What are your views on money and groceries - do you buy organic everything and he buys store-brand jelly? Does he wear custom-shirts and you wal-mart?
If either of you have a history of making decisions very early and then regretting them or changing them, or are both inexperienced at big decisions, I’d say that’s a warning flag. Timelines are irrelevant; it’s entirely about your comfort and how well you truly know the person.
Alice the Goon is half right - yes, studies do show that. However, the explanation is much more intricate: many of the couples who stay married and didn’t live together before marriage are people from religious backgrounds where it would be impossible to get divorced, despite their best interests. Another reason is lower-income folks tend not to be married (time, initial cost) and rather cohabitate for several years and raise children together, and then part ways. Another issue is the fact that (young) people are discussing less about the future and where they’re going before they move in together; with the cost of living being what it is, people jump to save money before they think out the legal and emotional ramifications. Are you thinking of the move to save money? Save time? Save “hassle”? Or because you want to entirely blend your lives together?
I can really clearly see this issue from both sides - when we came into the relationship, JulianSorel and I were both against moving in together before becoming engaged (the point you knew you were getting married). However, engagement isn’t yet appropriate for us just yet (family, money), so therefore for the time being we happily cohabitate. But before we moved in this summer, we knew we were getting engaged to in X amount of time, married in X number of years, that this is permanent. Over the summer one of his best friends moved in with his girlfriend, and is in the polar opposite position that we’re in - she pressured him to move out of the city, away from a place near his friends and his work and into a lower-middle class suburb where she’d just bought a house. He pays her rent (and is not on the deed), and for all the sweat equity he puts into the house and the part of her mortgage he essentially pays he gets nothing out of. At a recent wedding we attended, she confessed to me she’d forgotten to take her pill, and begged me not to tell him. So basically, she’s white trash, which is insanely bizarre, as the rest of us are setting up to be or already are white collar professionals.
If you do proceed, both of your names MUST be on the lease, you must decide that IF you break up, one of you will take the responsibility of being the one to move out (and will split the extra rent or something for the remainder of the lease, etc), and you must seriously talk about what this means. If to him it merely means he wants to be close to you, that’s all it is. But if you see it as marriage down the road (or, worse, if he “maybe” sees it as marriage, and you “definitely” see it as marriage) and he does not, you should seriously check the whole idea at the door.
