Google XML Sitemaps plugin and Webmaster Tools leave out urls

My URL is: lovephrasesx.com

I just installed Google’s XML Sitemaps plugin to my site and shortly after created a sitemap with 7 urls which I then submitted to Google Webmaster Tools. Google has only indexed 5 of the 7 urls I submitted.

Here is my actual sitemap all 7 urls: https://lovephrasesx.com/sitemap.xml

I know for sure that this url https://lovephrasesx.com/quotes-on-love-the-greatest-gift/ is one of two urls which Google did not index because I cannot find it in a Google search. It’s like the page doesn’t exists…however, if I enter that url into my browser addr bar, the article comes up fine.

Tried to determine which other url was left out by Google while I was inside Google’s Webmaster Tools but, I couldn’t display the urls indexed by Google on this site. Is there a way to do that?

In summary:

1- Why did Google not index all my urls contained in the sitemap I sent to them?
2- Is there a way to display the urls Google has not indexed which were a part of my sitemap that I submitted and they accepted without any reported errors?
3- Alternatively, is there a way to display all of the urls which Google did index that were inside my sitemap?
4- Here is my virtual robots.txt file:
https://lovephrasesx.com/robots.txt ; does this show or provide any clues in answer to my questions?

Thank you,
