String spacing on a classic guitar was standard om all guitars up until maybe eighty or ninety years ago, and of course still standard for classics today, so if you're having trouble with the strings being too far apart for you, it's probably because of your hand position.

This is a pretty good tip for finding the left hand position:   The Gorilla Grip. Internationally famous guitarist Sharon Isbin came up with this.

And for inspiration, to assurance that classic guitar fingerboards are well within easy reach of a normal hand in the correct position, take a peek at THIS!

Now, go thou and do likewise!

P. S. There's no law that says you can't have two guitars. I regularly use a classic, but I also have a steel-string when I want that particular sound. I don't have any particular problems with shifting back and forth.
