There were problems with Nancy and ALL of the children - at one time or another.. I think what it all boils down to is that she loved her husband to the TOTAL exclusion of everyone and everything else, and I believe he felt the same about her.. It was like they were on this honeymoon that NEVER ended.. A very powerful love that unfortunately hurt a lot of people along the way..
On the flip side though, I have to wonder how supportive the children were when the going really got tough with their Dad for the past 10 years.. I'm all too familiar with step-children who claim undying love for their Dad but somehow only manage to visit him when he's in the hospital in ICU.. Once he's out, they disappear again without so much as an occasional phone call..
There were problems on both sides - but the one thing I'm sure of is that Nancy and Ronald Reagan had one of the most powerful and enduring loves that I have ever witnessed in my lifetime..
