@Kissmark, I am going to make some guesses about how your skiing life has been going. Let me know what I'm getting right and what I've gotten wrong.
--It sounds like your family started skiing two years ago. Your husband takes the kids out to ski and you spend your time on beginner terrain by yourself working on building confidence and getting rid of that snowplow. Maybe you spend time waiting for the family in the lodge as well.
--You've been out on skis 5 days so far in these two years. I don't know how much of each day you spent outside working on your turns during those days. You've been using rental gear and you've taken some (maybe two?) beginner lessons. Those lessons taught you to make wedge (snowplough) turns.
--You thought that by now you'd be skiing parallel. You are disappointed with your slow progress. You're wondering if you'll ever get to ski greens with confidence since you are starting to ski later in life. Many here, myself included, started late in life. I started at 53 and others have posted their age when they started. So YES, you definitely can improve. Age is not an issue. And you need to know that skiing parallel takes longer than 5 days of skiing for many skiers, no matter when they started.
--How close to accurate am I? Please correct what I've gotten wrong.
Several things can speed up your improvement from this point onward.
#1. Boots that fit properly are the most important requirement for steady improvement. Most recreational skiers out there (
not the members on this forum) are in boots that are too big. If boots are loose in any dimension - length, width, height over the foot, cuff size, and so on, the skis won't do what your feet and lower legs tell them to do. Your turns will be difficult to control.
What constitutes good boot fit is not intuitive. To improve steadily without hitting dead ends, you'll need your own boots. Rental boots are notorious for not fitting. Buying on the internet or at a big box store may get you into boots on a budget, but those boots will probably not fit properly. Since you are a beginner you won't be able to tell if the fit is off. The solution is to work with a qualified bootfitter to select boots for you and adjust them to the anatomy of your feet.
Members here can give you tons of information on what to look for when you visit a bootfitter If you tell us where you are we may be able to recommend a particular bootfitter to go see. Who fits your boots matters. We may be able to help you find a bargain as well.
#2. Instruction that addresses your particular needs is the second most important factor for making steady improvement. Not all lessons are created equal. If you have had instruction for skiing in balance and with parallel skis, but that instruction did not help, you'll need to try a different instructor who can address your particular needs. A private lesson with an excellent instructor can work wonders. A private lesson doesn't have to be at an exorbitant price. You may be able to book a group lesson at a small ski area within driving distance during the week. Sometimes those weekday group lessons are taught by full time instructors with years of experience, and often the group lesson can end up having only one student. Such a lesson could get you getting parallel with better balance. It might be attainable at a bargain price. *Do not let your husband teach you. No-No-No! Do not go down that road.
#3. Deliberate practice, lots of it, is needed for real learning to happen. Change doesn't happen in a lesson itself. It happens when you do "homework" on snow by yourself. You'll need to practice what your instructor has taught you. You'll need to practice what you've been taught on easy terrain frequently and with regularity. More than 5 days per season may be needed.
You can do it! Skiing together is a great family activity in winter.
