Same thing here. The whole family on the W's side was all "we love and care for you" at the time of separation as they were not even aware of it happening. Now 3 months down the track, it seems that they have shown the side they are taking. So I have given up calling them. If and when I do speak to them I will be very cordial but nothing about the M or S. You certainly see who your real friends and family are in these situations.
