Embed Navigate WP Blog on existing website

Dear All

I have a website ( https://www.DummyExample.com) and I just installed WP blog (www.DummyExample.com/blog).

So Website url is: https://www.DummyExample.com and
Blog url is : https://www.DummyExample.com/blog

I believe 99% websites have similar structure. So far so good ..

However, Instead of having separate url (www.DummyExample.com/blog) for blog, I would like to Embed wordpress blog into existing website ( div or iframe) and allow end user to navigate on main website without going to https://www.DummyExample.com/blog for comment or to read single post.

So far, I was able to embed into existing website but whenever user clicks on comments or whenever he clicks on post title, it migrates him to actual blog url

May I know how can I make sure user never visits (www.DummyExample.com/blog) and complete all his actions (navigations) within actual website only?

PS: I do not want to remove from Post Title or Comments.

Thanks
Vishal
