Someone you've probably shared quite a few of your opinions with is your significant other. In fact you and your spouse may find yourselves at two totally different ends of the spectrum as far as your opinions go. Don't freak out though, it's perfectly normal. No two people are exactly a like. More often than not you will disagree on probably one thing, even if you both have similar values.
Sometimes the only thing you can do when you find a particular issue dividing is agree to disagree. I'm sure you have many friends that think at least slightly different than you. Remember that when you find out something that you and your partner disagree about. Sometimes it can be a time for the both of you to consider a viewpoint you normally wouldn't.
It's also good to keep in mind that sometimes people do change their point of view on certain things. It doesn't happen too often but it does happen. It may happen due to a life changing experience or perhaps something a third party said that gives them a different perspective than before. As human beings we're constantly changing, and sometimes our opinions do as well.
We might have opinions due to our upbringing or in rebellion to our upbringing. Now you may keep most of those opinions for the rest of your life, but I think most people will find their true opinions later. They might be further away from where you started, or they could be only slightly different than you thought before. Everything shapes your opinions.
That doesn't mean you should be constantly waiting and expecting the other person to feel differently one day. That's something that can't really be determined. You can't calculate your chances of the other person changing their opinion. If they do or don't often times has nothing to with you at all. So don't let that control how you feel about your relationship.
At the end of the day opinions are just that, opinions. Don't take them too seriously that you end up hurting your significant other. Because the world isn't going to end because he likes fried chicken and you don't.
P.S. In this picture we were having a disagreement on what color to paint the walls. I don't remember who won, but it's now like bright pinky orange.
