My ex has been relatively easy to deal with - but even he has the need, upon occasion, to contact me about little nothing things. I believe it's a way to touch base. They really don't think we'll move on and seem shocked to discover we do!
(And just one side note - I would have done the same as her about the riding without a helmet. My best friend's husband is in a nursing home with a brain injury from riding his bicycle without a helmet.)
