"Everyone has their flaws, you just have to choose what flaws you want to live with for the rest of your life."
My best friend told me these words one night when I was bawling my eyes out over an idiot boy. These words hold true for any relationship-- whether it is romantic or just a friendship. It is particularly accurate when regarding a significant other because all humans have flaws; it's inevitable, but it's which flaws you can't stand that are most important.
You can't change people, everyone is unique and lives their life a certain way and sometimes, things get complicated. Say you are dating someone and they love to sleep all the time but you don't. This could create some issues. This human naps all the time when you want to go out and spend the day together doing adventurous things. Is that something you want to live with for the rest of your life? Can you handle being with a human who gets off of work and goes and naps when you want to spend the evening together after a long day?
These are the things you have to think about because at the end of the day, you two are both going to stick to your usual ways. If these are flaws that you honestly can't stand, then this isn't the human for you. I'm sorry, but you can't fix everyone. You can't change people and get rid of their flaws to make them fit into the way you want to live your life. You deserve someone who wants to be in your life and whos big picture plan matches yours. In the end, you might still get a few flaws, but it is worth it because it is the right human for your big picture.
