When it comes to the terms of when people ask the question of whether or not a woman can change, fix or improve a man, and if how or so, in what ways, if you were to be completely and utterly honest, that's a bit of a wide and broad question based on the fact that that can be applied to and looked at in any category, or different and specific dynamics.
Ideally, predictably and assumingly, by looking at the question, it's talking about that happening in relationships or being hypothesized and tested for a relationship, but it can be applied to other areas as well, whether it be marriage, in which if or when the scenario in the question does happen, for some men it does happen in that area, friendships or opposite-sex friendships to be more specific and sound better, association or acquaintance or even parenthood, on the terms opposite-sex relationships with children.
However, to answer the question, yes a woman can change, alter and fix a man where he needs to be, on the terms of developing him and enabling to mature faster than a lot of men or the average man, since girls do mature faster than boys, or women mature faster than men, in a lot of cases and give him insight and knowledge on the terms of emotions and how women will react emotionally towards certain situations and circumstances, more in particular, when it comes to relationships and marriages, or even friendships, since women a lot of times or by nature, are the more emotional being or emotionally guided gender compared to men.
When you look at that in particular, that is and would be more suitable for parenthood, on the terms of a mother, especially and more in particular if she's a single parent raising up children on her own, especially if she has sons, with that being an current existing epidemic in the black community in the US, or the African-American community to be more specific and in particular, on the terms of the fact that a large percentage of young black boys, while also girls, grew up in houses or homes whether the mother was a single-parent, with no meaning or intention to bring up race and ethnicity into the picture and equation and although it’s another topic, but just to put it out there, raising up him or them to be a man that is or has the basic traits that are, a lot of times, seen by a lot of people as being masculine or expect to have when it comes to being the ideal man or male-partner for a woman when it comes to relationships and marriages, such as being responsible, independent, ambitious, disciplined, other than generic traits such as being smart, intelligent and respectful, even though women are capable of being that as well and you have women out there who are that as well, but at the same being sensitive, caring, compassionate, sympathetic and empathetic for people, with them two traits that being something that some, if not a lot of us men aren't very good at doing or being, in my personal opinion, more so coming and stemming off of personal experience, even though some people, men more in particular and also some women, could disagree with that, due to the fact you have some men out there that are very good at being sensitive, caring, compassionate, sympathetic and empathetic.
When you look at that, in a similar fashion, it's like asking the question of whether a single mother is capable of teaching her son how to be a man or with that question, it's in the same proximity as that and it deserves the same answer as to that question, on the terms of the fact, yes a single mother can teach a her son how to be a man, on the terms of teaching him the basic principles of life whether it being him learning how to be strong, independent, focused, but also getting him prepared for the big matrimonial, magnitudinal and important stages of life, with that being relationships and marriages, through teaching him about women, on the terms of what they want and expect from a man as a partner or soulmate, and how they think and act when it comes to certain common situations that they go through and experience.
However, if you were to look at differently, on the terms of certain stages or phases of life that can or will involve women that are capable of changing, fixing, improving or developing a man, going back to marriage, marriage, as I said before, plus parenthood, can alter and transform a man and for some men, if not a lot of them, more particular if they're the type of men that weren't thinking about marriage long-term, it does on the terms of waking up and being aware of what's in front of them and understanding what they have to do in order to stay successful or stable with that being a form of major responsibility, in this case with it being looking after a wife and children.
However, other than that, if you were to apply it to other social dynamics such as relationships and friendships, in those particular areas, it's not fully and completely possible or it’s not a 100% guarantee. The only form of action, tactic or technique, that I personally think a woman can use, do, take or that can work in order to change, fix or improve a man, that I think is or would be the limit for him or the best and appropriate thing to do for him, is the aspect of giving him words of wisdom and encouragement or words of knowledge and understanding to uplift him that can give him that spark or idea to change for his sake, if he’s in or going through a time of despair of hardship, or if it’s the case of where he needs to work on something that is either taking a negative hold on him, hindering him, pushes people away from him, looks bad on him, or gives him a bad reputation or perception of him by people, more in particular if it’s a bad personality or character trait that he has, or one that is seen by people as being unattractive. However, other than that or if looking beyond that, it’s not fully possible for a woman to change a man in that particular aspect.
However, that looking at that in particular, continuing to stay on the positive side, while also concluding at the same time, that shows you that when it comes to advice and help, help can affect and impact anybody, regardless of who is giving it and receiving it, with that including gender, especially if it’s between two people of the opposite sex, in which something that I reckon a lot obviously know, however, they take that fact for granted and not see the full power and depth of it.
