Hi All, OP here.
I know this thread is really old now but there was a bit of a development and now an ending if anyone's interested.
My friend had the baby June 2011 and apart from the party they came to with the new baby where they completely, and obviously ignored me (see earlier posts), they went on to have no contact with anyone from our social circle until January 2012 when the husband rejoined the rota for church activities that both he and I were mutually involved in.
At the first meeting it turned out that we were the first to arrive and I was quite nervous of what to say, as it had been getting on for a year since I had spoken to them, but he was totally fine, normal 'hey, how's things, how is everything going' etc and then throughout the meeting it was as if nothing had ever happened and he had never been away. That sunday they both came to church with the baby, but while he stayed to chat to people , she left immediately and spoke to no one.
They started coming to church semi-regularly after that and I saw him once a month at activities and he was fine, friendly, chatty. My friend, his wife, never spoke to me and I must admit I didn't try to go over and speak to her either. Some others did but she blew them off. She looked amazing though, she was even smaller than she was before the baby, had a new wardrobe and new haircut and looked very glam. Not like someone who was depressed or having problems adjusting to life with a baby etc, which is what I had thought might be the problem.
A few months on, so summer 2012, I was packing some stuff away after the service and she came over and said 'hey you, how are you?' I was completely taken a back and it was a slightly awkward convo. I asked how she was, was she back at work now etc and she answered but not in a chatty way and then said she had to rush off. It felt like major progress in that she came over herself, but at the same time it was awkward. Anyway, she did this to a couple of people over the next few weeks and so we started to invite them to social events again, but only child-friendly ones so they could bring the baby who was 1 by now. However they never responded.
By October she had stopped coming to church again as well, but her husband continued. Then at Christmas they sent an email to another friend in response to him trying to organise the next activity rotas with the husband, to say that they would no longer be coming and were going to attend a church in another town nearby. No explanation though, and they had been involved in our church and activities for about 8 years.
So, all in all, pretty weird. Was it us, was it me, was it church or was it something personal going on with them? Either way, we are unlikely to ever speak to them again. They are still facebook friends with all of us, haven't updated either of their pages in almost 2 years. I'd like to tie this up and delete them etc, but I'm not sure. I don't know why, it's not like they would care. Maybe it's just because I'm nosey and hope one daye they'll start updating again!
