Even if she drops out now and gets a job, usually you have to work for a while before benefits kick in. 3 months is typical, so you would still be working at your job for a while if the objective here is to keep medical benefits going.
There is no “right” solution here, you two need to learn how to discuss your options together and come to a solution that is ok with both of you. Neither one of you should play martyr, be careful that you are not doing that. The goal is to get both of you what you want. No one wants to be the source of their spouse’s misery - would you want her to work in a job she detests for you? How would you feel when she came home miserable every day? Imagine the roles were reversed. The spouse who has the horrible job can’t complain about it to the other, because that makes them feel guilty for putting them in that situation. The one who is benefiting can’t ever complain either, lest it turn into a “you think you have it bad? What about me…” situation.
Try coming up with a solution that has a definite timeline on it. Say, you will work in this job but only for X more months while you continue to look for something else that you like better. If you can’t find something in that time, she will get a job. Or something like that. I think you will both feel better if you just have a plan in place that makes you feel like you are getting somewhere, not stuck in this job indefinitely.
