Issue with Internet facing site and Intranet sites

Question

Hello All,
I have migrated the SP2013 environment using database attach method for our intranet site. We also working on the
SP2013 Internet facing site using the same content database as Internet site.
When I extended the web application for Internet facing site, zone to
Internet and these are the URLs: The Intranet website URL is
https://intranet.contoso.com/SitePages/home.aspx (Root Site) and
SP2013 Internet facing site http://contoso.com (not a root site and publishing site template)
However, I found on the http://contoso.com users can still access the
http://contoso.com/SitePages/home with same content as Intranet.
After done some Google search, bloggers mentioned to have move  https://intranet.contoso.com/SitePages/home.aspx to another site collection so that Internet facing site can exist root site.
Can 2 we have to two root sites in same web application? I need the content database to be same so that managers can check
Internet facing site and after signing into SP2013, redirects to
Internet site.  
Which is the best option to achieve this with same content database.   
Please advice.

Business Requirement:
Content Managers want to control internal Internet site (https://intranet.contoso.com) (with default zone, port 443, Root site) and also want to have SP2013 Internet site (with Internet zone
http://www.contoso.com (not a root site and publishing site template)), Anonymous access at Web Application level. I configured the site architecture
to have intranet zone as default zone and extended Web Application for Internet facing site with Anonymous site. This the current site architecture
Because content managers do not want to duplicate public site (Internet facing site) with will be shared with some lists that are stored in intranet site.
For e.g. a sub site named “News and Events” will be shared with Public site as well as Internet users. Therefore, if a manger wants to update a list in the public site, it should reflect in intranet site as well. Thus, managers
don’t want to have separate database but same content database.
Problem:
I have extended web application to have different Internet zone, the site URL looks this: http://www.contoso.com/sites/public with publishing template and Anonymous access. Managers want to have public site URL to be just
http://www.contoso.com and not   http://www.contoso.com/SitePages/Home.aspx. As I am using path based site collection for extending site collection, I am
getting this URL http://www.contoso.com/SitePages/Home.aspx
We also tried host named site collection, but it does not provide anonymous access and keep on asking for user credentials.
Q1: We want to have Intranet and Public site with same content database as per business requirements, Shall I following link       http://sharepoint.stackexchange.com/questions/81172/moving-content-db-for-a-site-collection-to-another-db-server?
Q2: Because I am constrained that I don’t want to have separate web application, (I know, its not regular requirement), how could achieve this requirements?
Q3: Do have to completely re-design web site architecture, with
www.contoso.com as main web application, then copy Intranet site collection and move this to
www.contoso.com/intranet using
Move-SPSite command 
Any kind of pointer and help will be highly appreciated as I am struggling for 2 weeks to solve this.
