Our son only lives 5 minutes away, but never thinks to call in on us, we decided that maybe we should try going to their house sometimes, so text to say would it be convenient to call in for a coffee, he replied with of course, but we both felt uncomfortable, the conversation didn't flow and and we felt we were just asking them questions, all the time.We have left it 4 weeks now, and he still hasn't been in touch, only to answer a text message, I'm beginning to think, they really aren't interested in us anymore.Very sad, and it hurts like hell..It does seem to be very different now, irrespective of distances they just seem overwhelmed with their own lives .
