People have many variant needs - spiritual, emotional, material and physical. When we get married we naturally expect that our spouse will help fulfill our needs. Here is a MAJOR yesod: No spouse will fulfill ALL of your expectations!
Example: She is pregnant and wants someone who understands her. HE DOESN'T UNDERSTAND YOU. He has never been pregnant never will be pregnant and never wants to be pregnant! You want to commiserate with someone who understands - call your friend Faige, she has already done this 8 and a half times [B'shaah tova!].
Another example: You, Shloime, are bothered by a perplexing Rashba [HALEVAI!]. Shaindee is NOT the address [unless she IS the address. If she is I'd like to meet her...]. Ask the Rov in shul.
Wait, but let's say that there is no other place to go? For example - he wants something only his wife can provide for him? What does he do now?!
Well, we know what much of the world does, but what does a Jew do?
Answer - THAT'S LIFE! You can't have everything you want always. Some people can't accept this, but we, b'nei Torah see it as an opportunity for growth. Denying gratification is a prized Jewish value.
As many of the other posts there is much to expand on but I will leave it up to the wise reader to think about it him/her self.
