I tell you right now, I'm in 3rd of university and that is priority 1 to me. In 2 years I'll graduate and I'll be done school forever. It's not like I'm a social reject, or don't like girls, I'd quite like to have a relationship, but at this point in my life I have to get a good education so I can get a good job and secure my future. No woman is worth throwing that away, and most women want more time than I have to offer so I stay single. That's not to say I'm unwilling to give a Woman any of my time, but it seems to me that most women want alot more of my time that I have to offer at this point in my life.
Sorry "Jane" but if "Bob" is like me maybe his Education is very important to him, and if you try to take that away from him you could mess up something he may be working very hard for.
Now granted I don't know this guy at all, nor will I pretend I do; but it's a possiblity that he is conciously choosing his education. The time you are in univeristy is a very small portion of your life, you have close to 40 years after you finish school where you work during the day and evenings and weekends are empty, and there is a short time of 4 where your life is busier. Some people look at University as a big party, others don't. You can't try and change that.
Now having said that, have "Jane" talk to "Bob" and explain her feelings. Maybe he's just a bit thick and doesn't realize he's neglecting her, but if it's a concious choice to make his Education priority 1, then "Jane" has to respect that. Even if she did change "Bob" is might really mess up his life, and make him resent her, and I don't think "Jane" wants that.
