Nope, that’s a myth that getting married makes you happier, http://www.belladepaulo.com/2013/04/on-getting-married-and-not-getting-happier-what-we-know/
And MOST SINGLE PEOPLE ARE NOT ALONE. They are more likely to have people who are still there for them, because they don’t count on just 1 person. They build their tribes. And just because a married person has a spouse or other family members does not mean that the spouse or relatives are not going to die! They are not immortal, just because they are relatives rather than friends!
Please stop perpetuating stigmatizing and untrue stereotypes. I’m done responding. You can find my perspectives on all of these issues here, writings on 53 topics relevant to single life: http://www.belladepaulo.com/2015/03/everything-you-think-you-know-about-the-benefits-of-marrying-is-wrong-the-evidence/
I know you value your own opinion/experiences over decades of research based on millions of people, but I can’t engage any longer with that.
