As someone who's been a shut in for what...4 years, trust me, it gets boring. You can only do so much alone all day.

It just sounds like you're unfulfilled - but i wouldn't say that giving up work completely is a good idea. We all need purpose and challenges, the right sort of work can provide that.

Maybe set yourself a plan; try something new for 6 months and if that doesn't work, consider going part time. If you're still not happy, try working from home and see if that gives you something interesting to do in the safety of the home environment.

Oh, and your husband can't force you to keep your job - if he needs you to be employed so that you can continue living together you need to see it from his point of you and work something out otherwise the marriage may be jeopardized. For example, would he need to take on extra hours just so you can be at home? etc. You're entitled to do whatever you want, after all it's your life and your choices but you still have to take your marriage and personal fulfillment into consideration. Best of luck.
