NC for this.
My DH loves to think the worst of things. It's draining and frustrating when he gets into a thought about something. (Which is not all the time).
His current issue is that DS will not get a job when he leaves Uni next summer, he will be back at home doing nothing (or gaming) for the rest of his life, that noone will ever give him a job of any kind.
He rationalizes his argument with the fact DS never had a part time job, looks alternative, is part of the LGBTQ+ community.
DS had top grades throughout school and is likely to get a 2:1 in an academic subject from a v good Uni. He's been actively involved with societies and events throughout his time and Uni has been a successful experience. He has a plan for after Uni. He has good friends (but quite a narrow community).
Of course, there is a possibility DH is right and this will occur, it's in the future, who knows, anything could happen? He might achieve his goals. He might take another path altogether. I don't know yet.
I explain to DH that there are lots of positives too, there is no point worrying about things that haven't happened and we have no idea if they will or not. I discourage him from speaking negatively to our son. DH says I am ignoring what's in front of me and he is just being a realist.
Any tips for dealing with a pessimistic person? Sometimes I wonder if he needs to get some anti depressants! I have suggested counselling to talk things over but he doesn't see any point, he says he just needs to prepare himself for his son's failure (& I should too). DH just wants him to be 'normal', which is unlikely based on DH's definition of normal.
