Endo - No you're not being over sensitive and even if you are, it's allowed at a time like this!
I had a variety of experiences with friends. My closest friends (two in particular) came round quite quickly afterwards, although probably not until at least a week or so. I was still very upset and struggled to hold it together when I was talking to them about what had happened, but it was like it was something we had to go through and their subsequent visits after that were far more normal. I did warn them that I was quite wobbly before they came round but that I did really want to see them. I think honesty is the best policy really.
Less close friends were a weird mixture. Some didn't respond to the message saying I'd had to have a termination. Fine, not everyone knows what to say but I must admit I have judged them harshly on this as I would never ignore such a message from anyone, no matter how casual a friend. Others did respond but only after a delay of several weeks, which again I judged them harshly on as I would never do that.
Others were unexpectedly lovely, surprisingly, as I didn't consider them particularly close friends before. One girl made a real effort to come and visit me in the early weeks as she knew I'd gone all agoraphobic about going out. I really appreciated that. Others sent unsolicited messages to see how I was, offered to drop in, go shopping for me, that kind of thing which really helped me feel generally supported. A couple of these types of friends said it had taken them ages to compose the 'right' message to text or email me and that they just didn't know what to say. I said that nobody had upset me by sending me a message, the only upset I'd felt was from those who'd said nothing.
My family were supportive, but mostly my sisters. My mum was terribly upset (not out of attention seeking, but because she has her own issues around pregnancy loss) and I didn't use her for support.
I think the best thing you can do for your DH is make sure he has someone to talk to about it all apart from you. Mine was supporting me, doing all the childcare for our daughter and still trying to keep working in the evenings and he didn't speak to anyone for a good few weeks. He then went out for a drink with a friend and ended up having a good talk to him about it all and he said he felt much better afterwards. I was quite relieved when he said that had happened as I was worried he was bottling everything up.
Whoops, this has turned into a massive essay! Hope it's of some use anyway.
