Oddly, some folks never give any positive indication that they do.
How the heck is the spouse supposed to figure that (s)he is loved, if all (s)he ever hears is negative blather?
One of the reasons I ‘turned conservative’ is the romantic notion that conservative men really loved their women and were faithful to them. While liberal men were ‘all about me and my needs’ and quicker to screw around and lie to their wives.
