Schengen-Non Schengen Combo For Year

Question:

In regards to the Schengen Law. I am from México and I want to stay in Europe all year round without breaking the law.

What about if I enter Schengen territory, let´s say Spain or France, or whatever. I spend 90 days traveling around Schengen terriotry. The I go and enter England and spend 90 days there or 180 since I get a 6 month turist Visa,

Can I go back to Schengen territory after that? I guess the point is, is this a way to stay in Europe all year round without breaking the law? 90 Days in Schengen then 180 days in England, and then go back to Schengen for 90 days?

Thanks
