I left and I always speak to the witnesses if I see them in the area and a few I stay in contact with. Some are more friendly than others. Some seem not to see me until I say hello. I haven't been invited to any social gatherings tho.
I spoke to the elders when I left, at my request. It took them 7 months from the initial request and several phone calls to them until they were able to find the time to come round. We discussed my concerns and I asked them if they wanted to disfellowship me and they said no. In the 7 months whilst waiting I stopped attending the meetings.
Since then I have had two elders call on me. One came round quite regularly and we discussed lots of different points, he changed my view of the trinity. Strange.
I don't think that it would be the same for everyone but I could be wrong.
