The reasons are many, but these are probably the top 3:

* Homosexuality is probably the most common reason, traditionally.

* Immaturity/infantilism is probably the most common reason today. A lot of the single men I see are those who are still very childish and lacking assertiveness, lack inspiring traits, ambition, self-reliance, etc... While there's the occasional woman who will be interested in taking on the role a grown man's mother, this is probably not very common, and not healthy. I see the "women are only interested in money" excuse, but the acquisition of money is a very common side effect of the traits I mentioned. Even well-off guys are not getting women if they lack ambition; yet, even very poor guys who have these traits have little issue getting women. Most women I know are not going to be interested in guys who are significantly less well adjusted to adulthood; they are looking for lovers, not man-children to adopt. The giving up on women that these men do are largely a side effect on giving up on being an adult in general. They might join the ranks of MRAs and incels just to have an excuse.

* General creepiness, a lot of guys are just creepy and negative people. Not only do women generally avoid these sorts, but everyone does. These are the sort that usually fill the ranks of incels and MRAs. Generally nasty people.

* Low sex drive is a potential fourth reason, but honestly: I know of no one who falls into this category.

In short, the main reason for guys "rejecting" women is actually the other way around. (Homosexuality/non-sexuality aside) It's largely an excuse that they adopt in order to avoid the truth that natural selection has rejected them.

"a person (usually male) who has a horrible personality and treats women like sexual objects"

hang on if these guys aren't getting laid, how can they treat women like sexual objects?

"theyre respectful to women and women are attracted to their personalities,"

i take issue with this to some extent, i've known guys including myself on certain occasions i suppose who women were attracted to despite not being respectful

furthermore i've known guys who wouldn't dare do anything to offend a woman, who women didn't regard even a slight bit as relationship options

i don't think that its a good idea to tell men that being respectful to women automatically makes them attracted to a man because for one thing its not true and secondly it breeds the same entitlement you seem to be criticing these "incels" of

men need to understand that just like men,, women are attracted to physical characteristics, obviously some cannot be adjusted such as height but physical fitness, hygiene etc can be improved

but i get the idea, sounds like guys bitter about not being successful with women, which i think could be a good thing if channeled into self improvement not self pity

Theres a few I could have chosen. I'm in a relationship, and I'm lucky that we get to do our own things even after 11 years get to game a lot. I admit I'm always tempted by the fruits of many others as I can't help be very attracted to women. You can't get more heterosexual than me. If for whatever happens I become single again it won't bother me will just be as happy. One night stands for me

I like how a few fake profiles come out to write some dribble because their partners are probably on the forum reading their real accounts lol

After reading more of the comments here is a quote from a great man.

"Let me tell you something you already know. The world ain’t all sunshine and rainbows. It’s a very mean and nasty place and I don’t care how tough you are it will beat you to your knees and keep you there permanently if you let it. You, me, or nobody is gonna hit as hard as life. But it ain’t about how hard ya hit. It’s about how hard you can get hit and keep moving forward. How much you can take and keep moving forward. That’s how winning is done! Now if you know what you’re worth then go out and get what you’re worth. But ya gotta be willing to take the hits, and not pointing fingers saying you ain’t where you wanna be because of him, or her, or anybody! "

Some dont want kids, and relationships can be devastating if they don't work out, most don't in the long run, out of the 50% that don't divorce most of those left just hang on

I have never dated and I never even started, I gave up at 16 after a few rejections and no date for high school prom. I questioned myself and decided dating is not for me. I see no point in chasing a pot of gold at the end of a rainbow. It is better spending my valuable time doing things that I enjoy in life.

Stares at self... :jordancry:

That is way to early o date anyway or most people. At that age I was busy with paying sport and doign stupid things to care about forming a longer term relationship.

Honestly you are better looking at something in your early 20s. By then you know the girls who have their head screwed on straight and aim for those. Avoid the dreamers who float wishing for something rather than making it happen

True in a lot of cases, but not all.

The simple truth is that courtship, romance, and sex are a competitive enterprise, and in every competition, there are losers. Hence natural selection. But not everyone who loses out is a seething misogynist who hates women. There are far more criteria than that on which women select their partners. Heck, there are plenty of misogynists who are successful with women.

20 years have passed since I accepted at 16 that dating was not for me. I assumed a few rejections = all will be future rejections and no point even bothering. I am the type of guy that quits something after one or two failed attempts. I quit my drivers license after 2 failed attempts and I have never tried for it again. I almost quit college after failing one unit, I got through the course but it was a waste of time and I wish I never bothered with college.   I take rejection/failure really personally. It feels like the end of the world and I am depressed about it for a very long time. Quitting reduces the stress/anxiety and I can move on with my life. I use avoidance to limit social interactions to reduce my stress/anxiety levels.
