This stuff is hard. Probably the hardest thing I've ever had to do. Some days I don't think I have the strength to do it. Some days I fail miserably. But I do it anyway. Laughter helps. And the odd bit of venting .
It does get easier. I promise. The ebbs and flows become just that, ebbs and flows. One day soon you will realise that although your H may not be in your life as a H, he is not your life.
