What do I do?

So, my fiance and I have been together 3 years. We have an 11 month old daughter. Our relationship has been only okay throughout the last year. We've been fighting and the last few weeks have been terrible and we've broken up like, 3 times in the last week because things aren't good right now. (No abuse or anything, just not getting along). We decided yesterday to put ourselves in both individual and couples counselling to work things out, but I think we're both a little skeptical still since we've been attempting to fix things for a year.

He lost his job about 4 weeks ago, and I've been supporting us. I have an amazing job as a massage therapist and while money's tight, were still doing fine financially keeping up with bills and our mortgage with a little extra in the bank.

He was offered a job accross the country and they need an answer tonight. He will be making slightly more than I do, but I'd have to give up my job here and restart my career, so initially, we'd be taking a big hit. Moving expenses, selling our house, ect. Also, if we ended up not working out, I would either have to move back across the country (My family is here and I would want to be near them) or I'd be stuck there with no friends or family, which terrifies me. It would be a huge risk for me since I have such an amazing job that I would never want to leave otherwise. I dont know if Id be able to get a good job down there. Plus my family wouldn't be able to see our daughter which I know would just destroy them. I can't decide if it's worth it.

Some pros to moving though would be that I would get to stay home with our daughter more. Housing is cheaper over there so we'd be able to afford a nicer place. His family would only be 3-5 hours away. Plus, job opportunities in his field are very limited, so he'd at least have something.

Our options are to:

A: Take the job and we both move across the country in a leap of faith for our future.

B: He takes the job and my daughter and I stay where we are.

C: He doesn't take the job and we cross our fingers and hope he finds something else closer to home.

I know it's weird to leave this to strangers, but I just want to see if I'm being crazy by leaning towards A.
