My first question to you would be - are you a church going man? If so - then other men in your church can help teach you these valuable skills. It isn't always about money - sometimes its about coming home to clean sheets and dinner on the table. We as females aren't any different from you. These assigned gender tasks are losing ground to a true partnership. It doesn't matter who makes the money, if today is her day to work - then its your day to make dinner and do the dishes. If she is off tomorrow, then maybe she can cook and do a load of laundry. It isn't about who does what - its about having enough. Enough time, enough money, enough patience, enough love, enough hugs, enough space, enough sleep, enough food..... enough. At the end of the day it doesn't matter who did it - it just matters that it needed to be done and it got done. Most women are just as touched by a man using the vacuum as they are coming home to jewelry - and the vacuum is probably more special since its cheaper and can be done more often!
She didn't fall in love with you for your money. But she will fall out of love with you because of lack of motivation in the partnership. Figure out how to be her complement.
FYI - if you aren't a church going man, observe men in your life that value their women and watch them. Spend time with them. Learn from them.
Get counseling if you need it - but get over the idea that you have to make the money. What you HAVE to do is support her, make her feel special and loved and valued. Its a partnership - not a competition. Work together so that your family has .... enough.
