Hey cofty,
If they stopped shunning tomorrow I think it would depend on the family member that shunned me and their circumstances as to whether or not I would have regular close contact with them.
Thankfully my parents were never JWs so they don't shun me and my kids stopped believing when I was Df'd my teenage son learned TTATT at 11 and my adult daughter faded at 19.
If either of my children would have shunned me I would forgive them in an instant and use that time to show them TTATT so if things change again they won't shun me.
If my parents shunned me and we're healthy and financially stable I don't think I could forgive them....but if they were elderly and vulnerable I would forgive them to help them in their hour of need.
It's a good question but I can't really say with all conviction because I love my family and we are very close despite WT shunning policies.
