My daughter died of cancer when she was only 9. I lived with her in hospital for months and saw her go through horrors that scarred my mind forever, then I watched her die. But I had two other young children. So I couldn't just bunk out of life. I hate going to doctor's. I mean, to the point of panic attacks. My daughter died in ICU. I have nightmares and PTSD as a result. But I go because my health is vital to my husband and surviving children. That is what adults who have responsibilities do. If I need treatment, I go see a doctor, nurse, wherever need to go to sort it out so I can do the best I can by my family.
Your husband is having you on. He has no intention of working. And looking after his children is not 'helping'. It is his responsibility as much as it is yours.
He dropped out of his course, he dropped out of his job, he burned through money from family members and he sits on his arse playing Xbox and going to football matches.
As long as you enable this behaviour, it will continue. You can kiss your dreams of SAHM goodbye and tbh, I think it's a really, really poor idea because you're married to someone who has proven he's not the most reliable when it comes to adult commitments like courses and work.
mummymeister and Stripy are spot on. He will not change by choice. You need to decide what you want and then put your foot down.
I wouldn't countenance his going back on the uni course. It's get a job or we split.
And you need to keep yours. Sorry, but you married a wrong 'un if you wanted to be a SAHM.
