I'm feeling bad because I just can't support DH in a decision he wants to make.

Background: We have 3 teenagers who are all very busy in sports, both have demanding jobs and are doing a whole house renovation project. He has been held back from promotions/job opportunities in the past as he has an associate degree in a job that typically requires a bachelor's.

He is very good at his job and an opportunity has come open that his boss has expressed to him that he'd like to give him, this would be a nice promotion. However he wants him to commit to finishing his degree within 4 years.

I just don't want to take on that kind of stress and committment. I don't think our life situation can handle that. We make a decent living as is and it's just not worth it to me. I know that if he starts taking classes he will want me to help him with the school work and I just hate that. I am in the exact same boat eduacation/work wise and I am choosing to accept the limits of my educational choices. If my employer wishes to advance me on the merits of my work performance I am grateful for that opportunity but I can't expect it. Yet DH is asking me to extend all that effort for his career advancement.

Add to it, DH is LAZY. I just can't see how he will accomplish all that he is committing to. Our house project is dragging on years past when we wanted to finish it(which stresses me out all on it's own). We will have one kid each year for the next three starting college and I'm stressed about that. Not only how to pay for it but all the details of getting there.

I am as normal for us the realistic one and he tends to be a romantic about things. I said all of this to him today(minus the lazy, I would not be hurtful) and he made it out to be just me being a bitch and not supporting him. Is that what I am doing? Should I be more willing to do this?
