The fact that you're having disagreements with each other isn't a problem -that just shows that there are some areas of your relationship that need to be worked on. And that's normal. People are different, so of course you're going to run into times where your differences come out and rub each other the wrong way. But what's important is that you both commit to work on those differences until both of you are satisfied. When you do that, you're walking the right road together and over the long-run you'll do just fine.
