Well - if you love him, then clearly you cannot divorce him. and if you are feeling so depressed, then you need him around. What would be gained by divorcing? - no company, no job - don't go there!! So.....talk to him about it and tell him how you feel. What you need is a joint bank account so that the money belongs to both of you.
We had this from day one, and we trusted each other to use our money wisely, and only discussed big items of expenditure. When we first married, I was earning and he was a student; then when the children were little it was the other way round; then when he had to retire early because of ill health I supported him; then there was a period when we both worked part time; and now we are both retired. All through we have had a joint account and it has never been a problem.
Do you think he would be happy with that?
Do you need to rethink your lifestyle?
We have taken some high risk career decisions in our time, valuing peace of mind and happiness over money and an expensive lifestyle.
Maybe it is time for you both to have a joint rethink?
