AITA if I tell my husband I'm no longer helping with house chores?

My husband (53M) and I (50F) are dual income, no kids and we do ok financially. He is already partially retired and working for himself. He makes his own hours and has a lot of flexibility. I still work full time at a semi-stressful job that requires a lot of travel. I love my job, don't mind the travel and I have a decent amount of flexibility most of the time. We have always kept our money separate and he's always made more money than me and is a very good save and excellent at investing. He pays for the big ticket items like the mortgage and real estate taxes and other big purchases, like our car and bigger vacations. I pay for everything else - groceries, eating out, utilities, car expenses and smaller purchases, like appliances, and smaller vacations. It's not quite evenly split, but it's proportional to our incomes. I've also taken care of my parents for the past ten years, so I basically no savings outside of my 401K and pension.

As we are inching toward retirement, we are having some issues around money. Specifically, we have very different relationships to our money. As I said, he's a saver and he's always looking for the cheapest way to do everything. While I'm not a flagrant spender, I am more willing to spend money to get what I want, when I want it. To explain what I mean, take the issue of our dishwasher. Recently, our dishwasher broke and I was glad because it was terrible and never got the dishes as clean as I wanted and I was glad to get something new. I did research on the very best dishwasher and what features I wanted. I went to look at a few in person and I chose the one I liked best. I waited until it went on sale and I got ready to buy it. I asked him to weigh in on it just to make sure he agreed that it had everything we needed. He dragged his feet so long doing research that we missed the sale. So we waited for another sale to come along and I put my foot down. Told him that I was buying a dishwasher that week no matter what and if he wanted an opinion to speak now. He finally settled on the same dishwasher I liked and I placed the order. When I was checking out, he said not to pay for installation. He would do it himself. Just get them to deliver. It was like $56 to have it installed. He refused. Said it was easy. It's not as easy as he thought. It took about two hours to remove the old one, get the new one into place and install it. Oh...and in the process he cut himself and banged his head. Luckily, this didn't result in a trip to the hospital like when he tried to fix the garage door, but that's a whole different story for another time.

Now, I've put up with this, let's call it frugality, for a long time and while it's annoying, I've just always dealt with it. But I'm starting to lose my patience. I'm at the point where I no longer want to do certain household chores. First of all, I'm not as flexible and agile as I once was so doing things like kneeling on the floor to clean a toilet just doesn't work anymore. My knees don't allow it. But it's more than that. I have just gotten to the point in my life where I don't want to do things that I don't enjoy doing. I'd much rather pay someone to do it so I can spend my time doing other, more enjoyable and worthwhile things. This comes up mainly in two areas - cleaning the house and doing yard work. I have been cleaning a house in some capacity since I was 12 years old and my mother assigned me the chore of cleaning the bathroom, folding laundry and vacuuming, and I'm just completely over it. I mean, I'll wipe down counters after I cook and wipe the toothpaste out of the sink. I also don't mind doing laundry and grocery shopping and cooking. But washing floors and dusting and vacuuming and doing those kinds of deep cleaning things - I'm just over it. And I HATE yard work. I always have. I don't actually mind mowing the lawn because it's a riding mower and I can just listen to music and drive back and forth. But weeding and trimming the hedges and spreading mulch - I just don't want to do any of it. And the bigger home projects like installing the dishwasher - let's just say that two hours of my time was worth way more than the $56 it would have cost to get someone else to do it.

Now, you might say "Fine, if you husband wants to do this stuff, let him." But it doesn't work that way. He wants me to help. Always. Usually because he needs the assistance because it's a two person job, but sometimes because he just wants me to do my part. And if I don't help I get the guilt trip about how he wishes that he had someone to help him This inevitably leads to an argument. So for years, I've just gone along with it. When he asks for my help, I go help and I try not to be too grouchy about it or have too much of an attitude, because that also leads to an argument.

But, you guys, I'm so tired of just going along with it. I'm so tired of doing shit I don't want to do. I work a lot with people who are retiring or soon to be retired and lately, so many of them are dying before they get to enjoy their retirement. I don't want that to be me. I don't want to spend a bunch of time I have left doing things I hate doing. I also don't want to live in filth and overgrown plant life. So here's my question - am I the a-hole if I put my foot down and just refuse to go along with it anymore? If I just hire a cleaning service and a landscaper? And if I do, how do I tell him that's what I'm doing without it being a major blowout. This is increasingly becoming a hill I'm willing to die on. I know if I sound like a spoiled brat and I'm being unreasonable you all will let me have it. So Reddit - tell me what you think!
