My parents have been very very unhappily married for more than forty years. They present a good front when with my own little family and my husbands but my Dad has a wicked temper, regularly tells my Mum how much he hates her, swearing etc. I haven't actually seen him hit her and I don't think there's ongoing physical abuse. I have been trying to convince her to leave forever.
Recently she has commented on a few things my Dad has done, nothing huge in the scheme of things with them but outside influences that have made him get even more aggressive. Fall out with colleagues (in his business that he basically sold fourteen years ago but hasn't quite managed to walk away from) , neighbour dispute over party wall and health news that isn't ideal, although not particularly serious). She's makes a few more comments than she usually does about him, his temper being "worse than I can imagine", he won't listen to her (he never has), and being generally wound up. She also keeps dropping heavy hints about coming to stay with us which so far I have deflected as my DP has had heart surgery so we are shielding and I thought it was just because we live in a nice almost seaside place. She visited yesterday again, on her own and I got a distinct impression that things are worse than ever.
I have tried to convince her for years to leave, quite openly, for her own happiness. But now it's got to the point where I'm actually here, a bit shaky, supping a beer and wondering whether she needs to leave for her own safety. I have ABSOLUTELY no idea how that would work, what to say, anything. Please can anyone advise me?
