Re: unhappy marriage.
Why does he not think its serious? Do you complain a lot? Do you cy a lot? Do you two argue and fight a lot? If you do, maybe thats why its becoming “just another fight” and nothing serious. Maybe you need to try talking to him in a different manner.
If you do not talk to him, what other method of communication do you think you have available to you? You want him to know how you feel but do not want to tell him? Is that right? What he is doing is wrong but are you making it any better? These are just things to think about.
His mistake is his attitude…so how do you make him realize this without talking to him? In this situation, fighting fire with fire will not work IMHO. You might ned to take the first step and be the bigger person.
