Resize the shape without effecting the proportion of text when grouped

Hi, does anyone know how to constrain text size/width in a text box when resizing the grouped object it is a part of?  That is, if I double the size of the group, or more than one selected object, I want the text to retain the same point size/characteristics no matter what.

I've tried everything - even ungrouping the text box from the other objects but selecting them all at the same time, and the text still scales/stretches.

I can't see a tickbox/option to force-constrain the text anywhere in AI - looked in the text flyout menu, area type options, etc.  I'm sure there is a tool/option somewhere - this seems a pretty basic command one would think, but AI doesn't seem to have it front and center anywhere.

I googled for answers too, but nothing of exactly this.  Thanks for any help in advance.
