remove title link on view page (or on frontpage)

I tested and tried many options and I succeed ! Here is, step by step, how I did to display a read-more link only for specifics articles.
if this can help someone...

1- Create a custom field in structure => Content types,
2- Choose your node and clic manage fields
3- Add a New field labelled "Read more"
4- Name it "field_read_more"
5- Select boolean field type, single on/off checkbox and save
6- on value : type "read more..." (it will display thereafter) - Off value : leave empty - and Save field settings
7- In "manage display" select in the format col and save

Now you'll see a checkbox below your body field (for the selected node) Check this box if you want to display "read more link"

In the views module, show Format as field, add title and body fields and the newest read_more field. Then output custom link with something like this :
<a href="[title]">[body]</a>

You're done !

Now if you checked the box below the body textarea in your content node, a "read more" link will display in the view page :)
