"The area I want to live in would be much more idyllic but further from extended family and from H (by about 30-45 minutes)...I know some people there but not well but it is a real community so I imagine we'd do alright."
Although it's not quite the same circumstance, since I just changed schools for my 6yr old S, I thought I'd chime in with my HO.
Changing schools is usually met with resistance by most kids & I believe becomes more difficult as they get older.
Going for the area you'd be happier living in will translate into a happier Alive, & more than likely happier children as well.
Living in most parts of L.A. at one time or another, my quality of life was considerably better & less stressed in Santa Monica, for instance, than Hollywood.
From following along here, I have no doubt that you will make a thoughtful decision that'll work for you.
Your children are really fortunate to have a mother like you!
