Jks, I agree with La Bug that you need to focus on doing things for you, and not so your H will notice. I am going to suggest volunteering as well since your L advised you not to work. It's a great way to get out of the house and it costs nothing.
Also, since your budget is tight, look for free or very low cost GAL ideas - check your local newspaper's weekend section for free museums, shows, etc. Lots of churches have free Mother's Day/Night out activities, which often include free childcare. I would say find one or two you feel comfortable with and start getting out. You don't have to participate in other church stuff if that's not your thing. But who doesn't want to take advantage of free childcare? LOL
