I live in The Netherlands and the commute here is about 1h, when I leave after rush hour. We have a requirement to work at least 2 days from home (higher management) and a request from direct management to work 2 days at the office when possible/workload allows it. Management here already noticed that productivity is higher when working from homeoffice, they even told us that when we want to work, we should do that at home. ;) (Office days are for meetings, so we can forget getting any work done)
What I do is during home office days is work a tad more, so I can make the office days a tad shorter, to compensate for the commute. Also, it's safer to drive outside rush hour, as it's a lot less stressing. Also I try to work from home as much as possible, which is allowed. The restitution for commuting is less then the actual costs, so it saves me time and money, more then working parttime would.
I would try to arrange that you'll be at the office 1h less on office days and compensate that during homeoffice days, although that's kinda hard with 3 office days and only 2 homeoffice days. Also, keep en eye out for a job that's more a dream to you then kinda a dream. No job is important enough to have a part of it stand in the way of your private life. Companies are usually a lot less loyal then employees. Most people work to provide a living for themselves and their families, not to keep them away from the family.
BTW never, ever, quit before you have something else. When a new company wants you, they can wait for the notice period. (and it sets you back when you apply for a job from an unemployed state)
