What does your husbby feel say about your thoughts? I would thin

need too much time and commitments from you then you can take care of it as a P/T, then find another P/T job as a start to steering to your real interest areas in the job market. It may take a little while for you to fit into a new job if you have beening working for yourself for a while already.

Anyway, it's good to give it a try if that thoughts have been with you for a while already.
