I don’t have a spouse, but I most certainly don’t spend my whole weekend doing chores either. I spread my jobs that need to be done each & every week out throughout the week. I manage to do that after work. If you want a weekend doing your hobby of home DIY, then you perhaps need to look at time management of the things you need to do. I would absolutely dread the weekend coming if it was purely filled with chores.
As for not wanting to go out with friends, if you wanted too, you would. If these friends are doing stuff that you don’t want to do, then it’s your choice to go or not. Making excuses for having too much to do, IMO, is not really the issue. By shutting yourself up away from people is also not healthy for you. If these friends seem to have little in common with you, maybe join a group of something of interest to you, so you perhaps have more in common. Time alone is good, but definitely not all the time.
