It's a common misconception that you must have everything in common with your significant other and that you have to agree on everything. Actually, it's been found that disagreeing and fighting occasionally is healthy for a long-lasting relationship. Now, with that said, if the two of you can't agree on anything, especially the major things, and you are always fighting, you might not be right for each other. But while you're busy figuring it out, people all over are trying to figure out the best way to help make your decision a little easier.
Sometimes love isn't enough to sustain a relationship, and that's a fact. But deep love and affection for one another is what keeps the world going 'round. It's also up to you to really decide what you're willing to put up with and what you're not. Society is (mostly) an encouraging place where you can be free to make your own decisions and be with whoever you want. Even if others don't think you're right for each other, all that matters is how the two of you feel about each other. At the end of the day, it's the two of you against the world.
