The first possibility is that your husband can't meet your needs, which is generally due to both physical and psychological reasons. The second possibility is that he has just come into contact with the internet and is relatively new. The third possibility is that the object of online dating is more in line with your imaginary husband, but I must tell you seriously that online dating is unscientific and generally will not have results. What's more, you are a married middle-aged woman. I don't know if you have children, but you must have a husband. Please be modest for the sake of your family.
