Junior,I am sorry to have to bring up these hard to accept truths. There are many men that go on to become programmers or engineers after literally years of zero female contact.These men think that they "found the one".Because they lack the social/sexual experience that "cool" 14-15-16 year olds got to have,they do not notice that subtle signs that there wife was promiscuous.You are either being naive or disingenuous. Literally people on temp think they are enlightened but they regurgitate the same mainstream thinking everyone else has. Women marry "nerds" for providers after they had their fun. Seems like you don't want to accept reality for what it is,I left some links in there if you want to read although you probably don't care to see the horizon for what it is.
Ever tried telling a man his wife is being unfaithful? Have you ever been lying in bed nude next to a woman while she calls her husband saying she loves him?Did you have early on romantic(physically intimate) relations as a 14-15 year old? All these questions are important to determine what experiences a man has on basing his conclusion. Late bloomers don't have the spidey senses to read women and they believe fairy tales much easier. I am letting the OP know my perspective from a person that has experiences,from a person that has friends that have bedded 40+ woman. This isn't a programmer that married the first woman to lay interest on him,this is NOT the perspective of a man that uses "beta bux" to attract women.
My perspective is coming from my personal experiences of being emotionally hurt since I started having sexual relationships in my early teens to my 20s with women of varying backgrounds and ages. I have had success and periods of draughts. I have been up and I have been down but whether the girl is 15 or 45 nothing truly changes. If you aren't socially adept you are going to struggle heavily with women. You need to realize most men never even realize when their wife is cheating and most men are desperate for ANY women.
