Woah, really?
Can't find a single one good reason why should anyone be judged while making decision about it's own life.
Friends are meant to be supporters, but seems they weren't some after all, nothing to be sorry for.
I lived for a long time alone, that helped me to learn how to keep myself a good company, nowdays it's very useful as I can not pull my dear darlings sleeve whole day around (sometimes I do heh).
It's more that inner feeling, hard to explain, it comes in waves and leaves fast. Learning to give everything time, right people will find me again.
Make your hubby to join some car club online or in person, you'll have more time to spend in your room. :p
