My boyfriend and I have been living together for a little over 2 years now. We'd been dating for less than 4 months. I'd always lived at home, and once he had moved out of his parents' house, he'd always lived alone.
Coincidentally, he had closed on a brand new house the same day I landed a job by him, which would enable me to make the move. Therefore, we were not only moving in together, we had to get a new house started, which meant a lot of decision making...from what kind of landscaping rocks to use to how to put the glasses away
We had some rocky times, but things are great now. Working out the little kinks and quirks is what can be rough, and it takes time. I could rattle off a list of things he does that annoys me, but I also realize that I'm not perfect either, and I bet he could come up with complaints too...even though I think I am just oh so wonderful to live with.
You also have to be understanding and willing to compromise. Pick your battles. Do I really feel like making a big deal out of the fact that he left his popsicle wrapper sitting on the counter, or should I just throw it away and be done with it? Some things just aren't worth bickering about.
We have two bathrooms, but only one is a full-bath, and that's really the best place to get ready. We each have our own side of the sink, our own drawer, and our own space under the sink. We also don't usually lock each other out, in case one of us has to get in there when the other is in the shower or something.
How do I distinguish it from marriage? As far as I'm concerned, the only difference is that I still have my own last name, and if we split, I don't get half of his stuff.
I find myself slipping up and calling him my husband sometimes, and he's already accidentally called me his wife. We have no plans on getting married though.
