I've lived with my boyfriend for 19 years. We have our own rooms, our own beds, and that's how I like it. You may think it's unromantic, but I'm getting the feeling you're quite young, and being in a relationship isn't all lovey-dovey all the time. Everyone needs their own space sometimes, and your partner can sometimes do things that get on your nerves, and vice-versa. That's not to say there's no real romance, but it's not constant and always sweet, the way I think you're picturing it.
