Why is the happiness and contentment of males so much more strongly influenced by successful heterosexual interaction than that of females? Most researchers today believe that the answer rests on the fact that women tend to be capable of finding emotionally intimate companionship vis-a-vis their own sex whereas men are able to satisfy their needs for emotional intimacy only in the company of women. Furthermore, non-dating females can normally manage to develop and maintain their socioemotional social skills and social self-confidence in their all-female peer groups. In contrast, non-dating males are usually isolated from social networks involving same-sexed peers.

Bear in mind that this was written a quarter-century ago, and for all I know (but don’t have time to research), subsequent studies have produced findings that mitigate or even contradict Gilmartin’s claims.
For example, Robert Glover’s No More Mr. Nice Guy groups have been providing stronger connections among men. The rise of the Manosphere on the Web also has provided men a chance to share their struggles with each other.
Also, since I’ve learned about “Game” and the “Red Pill” philosophy (thanks to bloggers like Heartiste, Roosh, Paul the King, Badger, and the Private Man), I’m more skeptical about Gilmartin’s theory — for example the idea that men need the love of a woman to make them happy seems simplistic and, well, “Beta”.
Like it or not, you might be on your own when it comes to happiness, regardless of your relationships. (And don’t anybody tell me “you don’t know what it’s like, being so lonely for so long” — ohhh yes I do, I’ve never had sex and never had a gf, there you go I admitted it). A favorite quote of mine comes from Richard O’Connor in his book Undoing Depression: “Happiness is not something others can give you or you can get for yourself, but a byproduct of living well.” [note, this might be a paraphrase and not a direct quote, but it’s pretty close.]
