Should I move back in with my parents?

I (28F) am a mother of 3 children (7M), (5F) and just had my last baby girl 3 months ago, during my last employment they let me go due to me being part time and maternity leave wasn’t available for my position. So the financial load fell solely on my Significant other

(28M), he has always had troubles working in the world due to a bad upbringing through foster care, drug addicted mother and all types of abuse growing up. So he don’t trust nor get along with anyone.

He just got let go from his current job a couple months ago due to them “not liking his personality, that it wasn’t a good fit in the workplace” so that has put us in a pickle, with both of us having a hard time finding new employment with it being the off season. We live in a very small town with few to no jobs available. My grandparents & parents have been helping us keep our apartment for the last couple months until we could find work. But here rent is overdue again and my boyfriend’s last check didn’t pay him enough to cover the whole rent.

I just went to an interview completed drug screen etc. so I should be hearing back from this job soon but my grandmother has offered to help pay the remaining $300 of our rent next week so we don’t lose our apartment but I just feel so defeated.. I don’t want my family to consistently be helping us pay our bills. I have a decision to make.

1. Move back in with my parents so when we do find work we can save up our money and pay back what we owe and save towards a bigger home for our little family.

2. Accept the money and pay the rent and try to find work asap.

What would you guys honestly do in my situation? I’m at a loss..
