Wow, thanks for the positive responses. I guess I'm just reluctant b/c I'm 31 and been out of my parent's house since I was 20. We all have a great relationship so I'm not too worried about that. I have to find someone to take over our lease though before I can do this!
Another thing, when my mom suggested it, she had our TTC journey in mind...she knows we have to have assistance due to the PCOS, so it would free up money to save for that too
Re: F/U to living arrangement post
I have to disaree with pp's post. Living there for a few months to get ahead financially can actually help them prevent future financial problems. Some parents view it as helping out their kids, being a parent, and doing what they can to help out. Being a parent doesn't stop when your kid turns 18. Now obviously every situation is different. But the op doesn't sound like a loser who goes back to mom and dad everytime something isn't peachy. Asking for help does not make you a bad person. Using the help available to you, and maximizing that help to get a step and making it clear that you are grateful for the help, is a sign imo of maturity.
