My wife was a SAHM because that's what she wanted and what I wanted. We each took on the jobs were were best at or that necessity forced us into. I was a finance major in college and a bargain hunter.
Example: My mom taught me how to shop and find the bargains. She taught me how to look at the ads and find the best deals and to find the best deals at the stores. She taught me by example how to bargain with the store employees to get discounts on the items they had for sale. My mom could pinch a penny until Lincoln would beg for mercy. My wife came from a family where shopping consisted of going to the closest store or the 7/11, buy what you saw and bring it home. It didn't make any difference what the prices were. You decided what was going to be for dinner and that's what you bought. My wife's parents thought as long as they had checks they must have money or they wouldn't still have checks. I went into the military and never knew when I might leave in the morning and get called to go someplace and not be back for 3 months. And if the mission was classified as "secret" I wouldn't be allowed to call her and let her know I was not coming home tonight. I had to teach my wife how to handle a check book and to keep it balanced.
You and your husband have to blend your lives together. You do what you do best and what you know. Your husband does what he does best and what he knows. You share the rest. I hate washing dishes. I like cooking. I am frugal with the dishes I use so there aren't more dishes to wash than what is necessary. And I can carry out the trash and take the trash cans up to the street with the best of them. My wife hates shopping, unless she does it like her parents did, which we can't afford, so I did 90% of the shopping until I retired. Now I do almost 100%. I taught my kids finances and shiopping. My wife taught them their ABC's. We both struggled with their homework. We both took them to church and taught them honesty, integrity, morality and how to pray. We did this by example. I taught my kids what a loving husband does for the woman he loves and cherishes by example. (5 of my 8 kids' spouses have come to me in private to tell me thank you for raising their spouses the way I did!!! That is a warm fuzzy feeling I'll never forget!!!)
Talk about it with your husband. You may both have expectrations that may conflict with your current reality. Decide who is going to do what and BE FLEXIBLE. Things change. Good luck to you and yours.
BTW, and I forgot to say this before, and its is most important for you and your husband... Your husband should be the most important person in your life. He was there before your kids and if it wasn't for him you wouldn't have your kids. Your children should be second in your life. Your parents and his parents should be third. Your husband should hold you as the first one in his life. His kids should come second and his parents and your parents should be third. And again . . . good luck to you and yours
