This has been a very emotional read this morning. So much pain and anguish from bewildered parents who are struggling to understand what's happened to their AC, and so much love squandered, because it's being rejected and thrown back in your face. There's a thread running through the posts, which is a sense of hopelessness and grief for the loss of a child who has grown to adulthood and put up insurmountable barriers, and you're struggling to understand why. There is also a reference to mental illness and a feeling that it gives some comfort to know that there is no blame.
Cherries I felt uncomfortable and emotional reading your post about 'splitting'. Uncomfortable because it was coming very close to explaining what my SiL is doing. I've never heard of it before, so thank you Cherries but I felt very nervous of labelling him in my head. I worry about how that may affect my DD and DGS in the long term.
hdh74 several things occurred to me whilst reading of the events of the past two days. My DM was always very sick and died two days after my 21st birthday. Her illness impacted greatly on my childhood, but I wasn't left feeling angry with her. I was left with a fear of being ill when my DD was growing up. I desperately wanted to be well for her sake. I was relieved when she reached 18 without me ever being sick. It seems your S blames you for that emotional absence when you were too sick to be at his beck and call. IF the way he is now is a result of him feeling your weren't there for him at times, he should be mature enough to know that illness takes over. We don't choose to be sick.
It's possible he resent his upbringing and family when studying in Oxford. If your DH felt it, then he's probably correct and that's sad. He would have mixed with people from wealth and all very bright, so perhaps he struggled to fit in sometimes, but how is that your fault? He seems to reserve his feelings just for you and that is very immature. Others have pointed out that he's being manipulative and he is, but he's using others to punish you, so they're being manipulated too.
You have poured out so much anguish in your posts and I urge you to begin to put some of that behind you now. I know from experience to keep reaching out to make peace and having it rejected is soul destroying. There comes a time when we have to say, 'Enough. I've poured out my heart to you and you are rejecting me. I know I'm not a bad person and I will not be defined by the person YOU think I am. I know who I am and that's fine.'
In my case, I am convinced it is mental illness which makes my SiL hate people in quite irrational ways. I happen to be the target. There are others he has tried to alienate.
You, your DH and your DD have had an emotionally intense few days and I hope you can begin to rationalise all those feelings which have risen to the surface. Have a few days recuperating and taking care of one another. Talk to us, talk to friends who understand.
Hugs for being brave.
