Allow me to offer my two cents as someone who's been around a lot of male suicides, feel free to take it or leave it.

Your husband has most likely been depressed for years, and as a result, has had some form of suicidal ideation. Depressed people, generally speaking, start to grow more on the idea of suicide. Look up the suicide scale, it's a very real phenemenon.

Please take this seriously. He doesn't mean to be terrible, but there is a disconnect between three things. Who he is currently, who he wants to be, and who he thinks he should be.

Has your husband ever self-depreciates himself to excessive degrees? Has he ever claimed he didn't deserve you? These are things to look at.

Self-worth and depression play into each other and one can cause the other. Stay safe, stay strong, and I hope you can get out this together.

To you it may seem like this is only a test at thing, but many depressed people suffer in silence for years before killing themselves. Especially if he has little to no self-worth.

Truly, best of luck.
