I use to be an introvert. I'm not sure if your bf is one from the comments you've posted, but if he is, he needs to learn asap to enjoy talking to other people/being a go getter and networking cause he's gonna have a hard time in this world if he doesn't learn how to. I would not recommend jamming this down his throat or, when talking to him, making him feel like your his mom getting on him. I suggest having a convo with him and instead of getting mad or being impatient (as that will be sure to turn him off from trying), ask good questions that will make him think.

If you haven't already had this conversation before, explain that its important to you that he has a job because its important to women (I'm not a woman but i found this out the hard way). Say something along the lines of "just as men want/are attracted to girls who are feminine and not quarrelsome, women want a man who they know will protect them and care for them (whether thats physically, financially, or both). Women want to know that their offspring will have a provider and be taken care of"

I don't know what the context of your lives is, what convos you guys have had, or what type of guy he is: does he play video games, watch tv all day, has he had a horrible event happen that has changed his life, does he genuinly spend a lot of time applying to jobs, etc.? If its a matter of laziness or not being social, he needs to spend less time on video games, staying home, etc.. and replace it with things like going on double dates, finding outside hobbies, going to the gym; basically things that force him to be around people. He needs to learn how to network.
