I can tell a lot of the new posters aren't even reading OP's update.
I'm going to go against the grain here.
OP's husband
Has bitched and moaned about every single job he's had for the past 14 years.
Has bitched and moaned about the lack of money.
Was excited about the new job.
Has spent the extra money he earns and enjoyed it.
Refuses to look after their son.
Refuses to deal with his double incontinence.
When OP mentions getting a job his first reaction is to tell her he "can't " take time off, he "can't " do holidays, he "can't " do appointments.
Does not do anything around the house.
Does not attend medical or school appointments for their son.
How the fuck is he the victim?
OP is seriously struggling with her mental health but working on it and getting slightly better and more confident. She definitely sounds like she does want a job. You know what knocks her confidence? A whiney husband that keeps telling her that everything will be HER responsibility because he "can't ".
It's funny how a lot of posters think it's fine that he won't look after their child or do anything around the house, but expect OP to get a day job or term time job to fit around HIM and still be fully responsible for their child and the house.
