Husband working 80 hr weeks

Hi There, can I please have some help with my model and thoughts.

C – My husband has been working 80hr weeks for 10 weeks
T – He needs to learn how to set boundaries and say no, as it is effecting his family/home life.
F – Anger
R – I become disconnected with otherwise I will be rude and snap at him

I want my feelings to be love and compassion.
Ive tried thinking ‘that he is doing this to support our family and I should support him’ and other such thoughts but it feels like I’m lying to myself and I just feel anger cos I want him to change. I realise I just need to change my thoughts but I don’t know how to get there.

How do I get to feel love and compassion towards him?

Thank you for you help.
