yeah,we have a set of twins,our first issue after 18 months of marriage.
i will never scold or insult my wife outside the bedroom,so the question of quarreling with her before my bros doesnt arise.
as per my bros and domestic chores,he doesn't help in anyway at all,absolutely lazy when it comes to domestic chores.But my wife and i overlooked that since i can practically play the role of a woman when it comes to domestic chores,i had rather help.
I am really learning alot from this fore-going.
From all sincerity of purpose,i appreciate your contribution,i have asked my wife severally why the constant quarrels between my bros and her,all she could answer was she doesnt like how my brother talks.
On the other hand,my brother thinks,i am not doing enough for him in terms of giving him money and these he thinks my wife is stopping me from doing.I have explained to him severally that i might be as rich as he thinks, after all i am only a salary earner.
I have also tried telling my wife to tolerate him,even when he talks thrash to his friends to her hearing,but she cant bottle that.
Like just yesterday,my wife over heard him telling his girlfriend that,he is not gaining anything from me apart from food and accommodation and that even the food my wife gives him most times wasn't what he wants to eat,my wife over head him and flare up.It took my land lord to quell the skirmish,since i was not at home.
Those quotes in bold just prove to me that your brother has no respect for you, your wife, your home nor the fact that you are accommodating him.
The person you need to speak to is your brother, not your wife. Your wife is doing her best, coping with his laziness (and cleaning up after him), cooking and having her efforts abused, and hearing his lack of respect for you. What other response do you expect from her?
You should appreciate that you have a good woman in your corner, but your brother has no respect for either of you and the longer he stays in your home, the worse it will become. You need to nip his behaviour in the bud, neither of you are his slaves.
Once you do that, if you have other siblings staying with you in future, they will know how to behave in your home, what is acceptable and what isn't. It's not for your wife to simply accommodate his behaviour etc, it is also for you to have a serious talk with him otherwise it looks as if he is walking all over you, abusing your home and getting away with it. And that really is where your wife's frustration lies.
I had a friend in a similar situation, her brother-in-law was equally awful and her husband eventually kicked him out. It was only when he had to struggle on his own did he appreciate that he had it good at his brother's place but abused it.
Your children and your wife are your priority. The sooner you can get him sorted out, the better, but don't let it drag on for too long. Good luck.
