I don't know if anyone will have any suggestions that I haven't already tried but would like a neutral perspective on this please. Sorry for the really long post in advance!
My MIL lives about 250 miles away in the same area as the rest of DH's family. We used to live nearby, but moved into the same area as my family 6 years ago.
My MIL was diagnosed with quite an aggressive form of cancer a couple of months before our wedding (wedding took place about 5 months ago). They tried to operate, was worse than they thought, so was treated with radiotherapy. She recovered and seemed fairly well. However at our wedding she had to leave after the speeches - having not eaten or drank anything - because she was experiencing what she referred to as back pain. I was fairly suspicious about this but let it go as she didn't want a fuss made. We went on honeymoon the next day, kept in regular contact, were assured she was ok. On our return found out she has all kinds of secondary cancers and that she had to start chemotherapy immediately. This seems to be having some effect, but she has lost a lot of weight, has been sickly, not eating etc. Frustratingly don't know about her prognosis etc because although my husband's sister and stepdad are lovely, they are both a bit dizzy and obviously very emotionally involved. MIL seems to me to be trying to downplay the situation, won't give me a straight answer and seems to be trying to 'protect' everyone (husband is almost 40 and sister a few years younger so I think this is a bit misguided).
The issue is that my husband has not seen his mum since our wedding day. He doesn't cope with these kind of situations very well and bottles up his feelings. I don't understand this - and it has caused lots of arguments. I have tried so hard not to argue with him about it but he finds it hard to talk about it without lashing out at me (I understand this is part of the way he is dealing with it). It eventually came out that he is worried about seeing her in case she looks too ill (?!) and he is scared that she is going to die... he keeps making plans to visit, but then cancels them after finding an excuse. I have tried everything to persuade him - gentle cajoling, offering to drive him there (he doesn't drive), pay for train tickets... I'm conscious not to talk about it all the time but I'm worried about what will happen if things take a turn for the worst and he hasn't spent much time with her. I know it will be awful.
The worst thing is - and I really regret this - after a few glasses of wine I shouted at him "When your mum dies you will regret not spending more time with her!" which is just horrible really - but I feel like I am getting to the end of my tether with it all. My sister says she thinks I need to leave him to it, but I can see how much he's struggling to cope with it and it's really upsetting...
