Posea... the main goal of this forum is to give useful advice --- advice that will help improve relationships, or individuals themselves, or both.
In the process of doing so... you have to realize that though some may come here asking for advice... what they're really looking for is validation for how they 'feel' or some kind of misconception they have. It's up to us... those who give the advice... to not only offer such advice... but to present it in such a way they cannot dissect the meaning and pervert it to justify their misguided stance on the issue.
Whether you are right or not on the trivial piece you mentioned is irrelevant. All that matters is the fact that you presented your 'advice' in such a way to where the OP could use it to validate his poor choices and selfish motivations. His marriage will surely fail and he will miss out on an opportunity to learn the lesson he so desperately needs to learn --- self-discipline.
