Coastal I think some people are so wrapped up in their own lives that they show some sympathy at first, and then as their life moves on with their day to day troubles they forget (whereas for you of course, what you've just been through is ever present and still everything to you...).
I only told my oldest friends who said all the right things at first, but then nothing really since. I put it down to it being because I wasn't very far along in pregnancy, and thought if I'd been further along people would be more concerned for me (and rightly so, it would be worse of course.) But it's nice when someone just says 'hi, how are you feeling today?' Isn't it. Who knows, human nature I guess. One friend, the one who I'd told first, text me from her holiday a week later saying her life was shit and everything goes wrong for her, because her case had gone awol and turned up next day (this is bearing in mind we'd cancelled our holiday only the week before as was due to fly day after we went to EPU, my LO got chicken pox as well so all things considered we couldn't go). I read it and thought, well I'd love to still be pregnant now, on holiday or not, with or without a missing case!
Your OH sounds very supportive though. Mine was great at first, and is very supportive in general, but mostly In a practical sense. After his initial upset when it happened, he looked after me for a couple of days and then moved on fast. He focusses on the positives 'it's fine, it'll happen for us' we'll try again straight away, etc etc. When sometimes you know all of the positives, but you just want how you feel acknowledging. Hope you're ok today x
