Let's face it, it's just normal, and we have to live with them!
Further, we need to appreciate them! We are not perfect, but it's not necessarily bad. I am not trying to speak good for evil, what I am trying to say is that, we are just human being, and we have our limitations.
Our spouse couldn't be perfect, and at the same time, it could be our imperfections which brought us together! We can help each others. If our spouse is perfect, s/he does not really need you, and might not be able to appreciate your existence.
So learn to love our spouse, completely. By complete, that includes the strengths and of course, the weaknesses.
