It does get better. After our daughter was born I could probably have counted on one hand the amount of time my wife and I had sex the following year. I was jerking off like no tomorrow haha. Fast forward a couple of years and the sex is more or less back to what it was like pre baby.
You think that everything is fine once your children are grown and move out. And then at age 35 they decide to move back home. And you find that your routine is totally turned upside down. Your way of doing things is no longer correct. Being how you pay your bills to how you clean the house. And God forbid if YOU should have company visit. It ruins THEIR plans to have people over . Going to bed at 10 or 10:30 at night is" too early " They will stay up till 1 or 2 am or later. every night. Drinking beer and watching TV. And then get upset because your up before 7 AM making noise in the kitchen. Yeah. I will take a young toddler over a 35 year old who feels that they know every thing any day.
What sort of sado moves back in with their parents at 35 haha. There would be stern words if I ever found myself with that dilemma.
At different times my siblings both moved back in with mum and dad in their 30s. I'm proud I've never done so and never will.
