Phizzy~ also, things may ebb and flow with you and your family. Things... emotions, thoughts change.
Personally, it has been hot and cold between me and my family since I left five yrs ago. There have been heated discussions...other times I would hug them or say 'I love you' and got nothing....times when they wouldn't make it possible for me to see my little sister...
then there were times that they would say 'I love you', 'we think about you'...send letters...call to check in on us...sometimes we would even laugh about things
..there were times that I would not allow my family to have contact with my daughters...didn't tell them we moved out-of-state...didn't answer phone calls...
then there were times that I would just spontaneously call them and had a short but calm conversation that felt warm and simple (even if emotions run deep inside)
Guess what I'm saying is that there is no natural way to be when dealing with the unnatural forces of shunning. You may find yourself trying different ways of being, to cope with the frustration and pain. Who knows how you may feel six months from now? Maybe you'll be more indifferent. Maybe things will calm down and you'll find a way to have a little bit of peaceful contact, leaving the door open on your end. Maybe you'll say something direct and make them think.
I feel you on the twinge of guilt about 'shunning'them back. It doesn't feel right, but it also feels like sometimes it's the only way...at least for some time. Sometimes it's best to create some distance from where the insanity is coming from. Who wants to feel like they're constantly being rejected? Especially when it's so unfair. It can mess with the psyche. Maybe when you feel more grounded in your life away from the insanity, you'll feel fine letting them back in your life...on your terms.
