So married women feel sorry for us. If it was not for their support, I would be in a mental hospital now. I know two have my back.
Then why do other women treat us like yesterday's garbage when we just walk in the room?
Partially true.
Women do not feel threatened as much with us near or talking to us when they are married, as they know they may be able to approach or talk us without feeling like they will be hit on (asked out or flirted with) as much, and they know they have one or more excuses on their side to not get too close. This may allow themselves to be themselves more, relax more, empathize more, and to show their nice side more.
Women who are married may take more risks in talking to single guys by acting more friendly, as they feel the expectations will be seen as different with the contact. They know that the encounters need not be perfect and will likely not lead to much other than a friendly exchange or possible friendship. Married women also could less fear being judged adversely by others if they talked to one who was not their type, as they would think the others would know they were already in a committed relationship.
I however do agree single women may unfairly negatively judge single guys or assume too much for those guys who are friendly to them or who even just stand or sit near them. Is this guy safe? Is he my long term type? Is this guy trying to date me? Does he hope for sex with me? Could he stalk me? What is this guy's job? Is he financially stable? Is he married? Why is he near me or looking at me? At times they may overthink things or put all guys in the same basket, thinking they want something more than just be polite, friendly or social.
What women may often do is to size guys up quickly. They not only look at what he says or does not say, but how he says it, his tone of voice, his posture, his facial expressions, his other mannerisms, his attitude and they may put that into context with the setting and what he did just prior, to determine what to do or to make of his doings This may give her some clue to finding more about him, his intent, if any, and if he is suitable for her in any capacity, like for a quit chat, or as a potential friend or future partner, etc, or if it is best to just avoid.
I do not think most single women have any malice or ill will towards guys who do not meet their expectations, but most do seem to act very differently towards single guys and married guys, and for guys who have some traits they are interested in quickly versus those traits that they think or assume would be not for them long term. Many single women may not even need single guy friends, as they may feel they have women for that, where they feel more comfort to express, or to feel more safe.
So, unfortunately, yes, many single women may not give the time of day to any guy who does not stand out in a very positive way rather quickly, unless talking to them through less direct communication means. That is why I myself never approached single women in person. Either they approached me if interested or I communicated online with them well before we decided to meet. This gave time for both to know each other, without premature judgements.
However, women can judge a person's writings too. Is he too negative? Does he talk about or show through words what he brings to a relationship? Are his interests interesting? What does he do for fun? Does he have much baggage? Does he seem responsible and hard working from what he says. Will he be compatible with me in person too? What is his living situation? What are his goals? What does he want in a friend or partner? How does he act under stress, etc.
I do feel women thus are more complex and needing of the right situations. I understand often their concerns and needs thus there, but I do empathize with guys who cannot meet societal expectations of what a guy should be. It is far more common for women to be allowed to at times not offer as much, or for them to be allowed to be more themselves without added pressures to do more that they can do. I do think though more and more women are realizing that traditional guys are not always the best long term partner material, that nicer guys can be safer and more supportive and loyal. I hope more will understand that at least as women advance and more guys are allowed to help in other ways.
