Oh Whiff, it's so hard when you get used to coping with no contact and then there is minimal contact which leaves you confused. I have no idea what's going on in your son's head, any more than I have what's going on in my son's, but I totally understand the power of these moments.
Welcome Lkathryn. This group has helped me more than I can say since my son estranged me. I do hope it does the same for you. My own son suddenly estranged me after starting counselling, and gave me no reason whatsoever. Only recently, after waiting several years, did I finally get a letter a few weeks ago. I have to say the things he said seemed totally inaccurate picture of our lives together as he grew up, not just to me but to my family and to a good friend who has known us all these years, but as it was all in very vague terms I asked for some specifics. I'm still waiting.
You will find some people who have reunited, and others who have made their peace with not doing. I know in the early days that seem impossible, but however things work out for you I hope, and believe you will get a lot of the support you need here.
