BM thought we would divorce inside the first year. And here we are, 10 years into a great life.

The sad thing for DH is it is also my birthday and his sons have not even squeaked out a text to either 'H/Birthday to Oneoffour" or "Happy Anniv Dad". He thought they may text something. But they haven't. I told him it doesn't matter. My kids remembered, even my estranged son in Australia without provocation F/Booked me Happy Birthday. And I am not SSons mother. I don't have such expectations of them at all.
He said that he always remembered his parents anniversary. But I am not their mother so why would they even care? Because it involves their father? Not likely!

He is finding out slowly that his sons really don't care. Until the next vehicular emergency... And then we will be busy. Very busy.
