Same here , but in my case its even worse; I'm caught in a rat race to fetch my 3 kids after the 16km return home; so I still need to use my car (SUV) to transport the bike while I get the kids and do the remaining 15km by car. Fetching the kids by bike after 31km would be too much; I choose my battles

I guess I'm masochistic. I get fit though and its pretty much the only time when I can feel like I'm doing something for myself (ie: besides work, kids & sleep)
