<human>: Let me preface this by saying I love my boyfriend and I know you shouldn't try to change people you love. We've known each other since we were kids and the friendship turned into love. 

That being said, there is one thing about him that drives me crazy and has me seriously considering breaking up with him. He has no motivation to better himself whatsoever. I'm a grad student on a phd track and he just recently lost his job and is now working construction. It doesn't bother me that I'll be the sole breadwinner in our relationship, but it does bother me that he doesn't want to improve himself in any way. He's not interested in applying for better jobs, or getting an education. He makes jokes about me being his future "sugar mama" after I get my degree. I have very specific goals that he has said he wants to help me reach, but when I ask about his goals or dreams he says he doesn't have any. He is the most lethargic person i've ever come across. He doesn't even get all that interested in sex, I always have to initiate it. How do I confront him about all this without telling him he has to change or I'm going to leave?

Can you summarize the given text in a few sentences?
<bot>: My boyfriend is very unmotivated and I'm thinking of breaking up with him. How should I confront him about this issue?
