Why not do the following:
Tell your present instructor that you're thinking of moving to another school where you have friends and that's easier to drive to. Tell him if it doesn't work out you'll come back. Thank him for all he's done. That way, you leave on good terms (which I gather you are!) and can go back.
Move to the new school, and see how it goes. If it's OK, why mess around with two schools.
If you don't like either the school or the instructor, go back to the old one. At worst, you'll have learned a bit about different airfields, schools, and instructors.
In the long run - and you have most of the course to go - you'll find it a lot easier if you find one school, and maybe one instructor if you can, and stick to them. But there's no harm in shopping around.
Good luck whatever you do - and enjoy it!
