From someone who once supported a boyfriend by working 3 jobs and care taking, while he "waited" for the right opportunity to come along... Here is my two-cents.

1) Maybe you need him to be supportive by getting a job and paying half of the bills?
2) You might be able to take time to sort out your issues and work on yourself if you did not have to work 3 jobs?
3) MAKE time to go to see someone who can help you figure out what you need to do to feel better and more stable

I hate to say it, but the best thing might be for you to go your own separate ways for awhile until you can both get to where you need to be in life before being in a marriage.
