I have been exactly where you are. I could have written that post myself. I don't have a job and I'm in school full time, so I'm definitely spending way more money than I'm bringing in. I don't like to cook and I'm terrible at cleaning (perfectionism gets in the way...). The one household chore that I don't mind, maybe even like, is doing the laundry. Probably because I can do homework while it's in the wash and dryer, and then sit in front of the TV to fold it. But anyways, my husband is fine with the way things are. He sees his paycheck as our money, not his. He takes care of all the bills, the credit card, and my student loans (his student loans are a drop in a bucket compared to mine..). But if he wasn't getting something out of keeping me around, he wouldn't have married me. He wouldn't still be married to me. I think part of him enjoys being able to take care of someone. But he tells me he needs me too, that I bring emotional support. He enjoys going for runs with me, going to museums, just talking and spending time together. I make him happy and he doesn't get caught up in all the little details. I also make a mean chocolate souffle... maybe that's the real reason he keeps me
I agree with what everyone else has said about it being linked to depression and low self esteem. Since I started feeling better, I haven't had as much of an issue with feeling like a burden. I still have some guilt over money, but that started long before I met him and it's not about to go away over night. Try talking to a therapist.
I started feeling better when I started running. I think part of the reason it helped so much was because I was able to set goals and achieve them. And there's that whole runner's high thing going on, too. Also, and this might be a little extreme, but would you two be financially stable if you quit your job? I think if you quit your job and did some volunteer work that you are passionate about while you look for a new job, you might start feeling better. If you're enjoying your work and feel like your giving something back, not necessarily to your husband, but to the community, it might start to bring back some of that self-worth you've lost. And hey, that volunteer work could lead to a permanent job down the road.
