6 months

I need advice. After my husband(33m) cheated on me(34f) we made plans on how we would do things moving forward. He is paying for my rent and all my bills but because he does not make much(70k)he will eventually need to get his own place and he won’t be able to juggle all the bills, so he gave me 6 months to find a job and then we agreed he will give me child support. In which, I think I’m beyond nice on saying yes but because this is my children’s father, I don’t want him out In the street either. Anyways, so now I never finished my nursing career, I do have an associates in science but no real career. What kind of job can I get that pays good or that I can get a certificate in the next 6 months? Also I am in Texas.
