And so it begins... or ends?

We are separated again.  By separated, I mean sleeping in separate rooms.  No physical contact whatsoever.  Saying "excuse me" when we brush past each other in the kitchen. 
The boys can sense something's up.  They are 2.5 and 1.5.  More Easton, the 2.5 y.o. than Mason, the 1.5 y.o. 
We are financially stuck in this house.  We think we can separate w/in the next 9 months or so.  I have been a SAHM for 3 years and need to find work.  NOW.  I have my teaching license, but no experience.  I got my license last time we separated and knew that I would need to get a job.  The boys start daycare in Sept. so I can substitute teach and get some experience.  With the daycare cost, I'll be getting paid about $5/hour.  Great, right?  *sarcasm*
We have a rental house in addition to this one.  Total of $5k in mortgages each month.  He makes over $100K/year right now, but is retiring next year w/ a $38K/year pension and is planning on going to law school FT and work PT?  I have never agreed w/ this idea.  I think it's frivolous as we have two children to support.  If he does this, my child support will be about $800 less than it would be with a regular job.  I don't know that I can make ends meet with the child support from the pension.  He says that it's something he's always wanted to do and I won't stop him.  He's 42 y.o.  I'm 36.
Should I leave here and go back to live with my parents (5 states away)?  I don't want to take my boys away from him.  I love them more than anything in the world and he does too.  I want them always to be with both of us.  Should I be looking for teaching work in another state?  Can I do that when the stipulation of the licensure program I went through said that I had to work in VA for my first year of teaching at least? 
I have a consult w/ an atty this afternoon at 2 pm over the phone.  I just need some kind of plan. 
So confusing, so scared.  I feel sick all the time. 
I just needed to get all this out.
