Re: unhappy marriage.
My friend,
First, men usually do not cry.
Just because women cry, men do not.
Men do feel bad and understand the situation in general but usually it takes a lot for a man to cry.
OK.
The issues you have brought so far have been very much usual and trivial and yes you do seem to be sensitive. Not that most women are not. Yes they are.
I think he wants to see you as strong person and happy and does not want to encourage you to be so sensitive.
He does have a choice to come to you and show you his affection and be lovey dovey but it might be that he feels you need to grow out of your behavior on your own and be tough.
Don’t know what is the difference of age between you two.
**Most men do not show their affection like most women do. **
The moment you learn that, you will feel relaxed and take things more realistically.
It does not appear he hates you or wants to hurt you deliberately (based on yor posts). By this time, you must realize that being upset on these matters is only going to hurt you and your well being.
Try to get over it. Keep the love going in the relation. Keep your head up and enjoy the relation.
Show your love to him not by crying in bed alone, but call him to join you in bed. J/K 
Also, crying never helps except clearing eyes of dirt and maskara! 
**Even if a he does not show affection by words or actions, he may still love you and he will be there to protect you from any real life issues. **
