OH & his sister fell out a year ago over their late mother's estate. It has all been sorted however they haven't spoken since. SIL at the time rang asking to speak to OH. He wasn't here so she became hysterical on the phone and threatened to never speak to me or our DDs again. I have spoken to SIL a couple of times in passing but nothing more, until Xmas eve when I dropped round some presents and was invited into their house and they all behaved as if nothing had happened. We have no other family around and I think as a year has passed we should try to move on. However I spoke to OH about this today and he said unless SIL apologies for threatening me, he still will not speak to her. AIBU to contact her and say that we would like to start having contact with her & her family but ask her to apologise? Not even sure that she would mind you!
