People won't acknowledge the reality behind this, but it's because the barrier to entry of being a successful/accepted man in society is much higher than it is being a women. It's not a matter of fairness but reality, men are disposable women are not. It's what I call the "social ticket" (how much innate value do you have to others based on looks and status) The average and even the below average women will have dozens of suitors whilst if you're a below average man you're going to have next to no options and if you do get a romantic partner then there's a good chance they may end up leaving you for someone better. What does this mean? men of this value have no reason to participate in society hence they're more lonely. It's not even just that, it's because people don't want to be friends with low value men and if they're your friends there's a good chance you'll end up being the butt of the joke. I have experienced being both a man of high value and low value, in highshool I was very tall for my age and my only good quality is my exceptionally deep voice, because of this I got a lot of attention from women and people treated me well. Now as an adult I'm below average height, extremely skinny (I'm not kidding I can't even wear clothes normally), have a deeper voice (I sound like some kind of sophisticated news anchor) I have a handsome face, it gets the attention of women but when they look at me physically they don't like what they see hence the consistent coyness I've experienced my whole adult life. It's like, if only you were this much better looking they'd actually desire you. I also get treated much worse by people in general although I've always experienced this due to my unconventional appearance.
Another reason is male socialization, we tend to be a lot more independent minded and less socially inclined like most women leading to a decrease in relationships formed.
