When you say to someone that you have an argument-free relationship, everybody could just envy you.
But every healthy couple simply has to come to a situation in which they have an issue they need to resolve or when they disagree on something.
But even when that happens in your relationship, it seems that your partner is never interested in resolving your problems or in talking your issues through.
It’s like he never cares about getting to the bottom of things and like the outcome of your relationship doesn’t bother him.
Although in the beginning, you thought that this was a great thing, with time, you’ve grown to realize that he is simply not interested in dealing with your problems and that he is not interested in making your relationship better.
