But many of these suicides, such as in my friends situation (RIP) wasn't because of loneliness was because of having his kids taken away from him by his ex. Or in other cases, men loose their job, get into financial issues so suicide is their only way out.
No it's not. They may see it as their only way out but that's not the same as it being the only way out.
Now your friends kids have no dad because of the selfish actions of said dad.
Suicidal ideation is fine. When you are at your lowest point in life, these thoughts can form and feel quite reasonable. Acting on them is another matter especially when it will affect others e.g. family.
Given the demographic of this forum I can bet that quite a few on here have had serious suicidal thoughts and never carried them out once things are rationalised.
I do agree that male suicide is a national disaster however. Perhaps if the same level of advertising/discussion on this as there is for other demographic's problems, it may lower it.
Instead, the current discussion in the UK is how bad men are and that they must change without identifying the root causes and supporting that change.
