<human>: Could you distill the essence of the text into 1-3 sentences?

Our parents both own homes in the same cul-de-sac so we live about a stone's toss away from each other. We started dating about 7 months ago while he was still a busy college student (just graduated last month). He currently has multiple ventures selling different electronics and memorabilia, has a job (not sure anymore as his mornings are mysteriously free all of a sudden and he hasn't told me anything) and just started interning at an investment group. 

I know he's really busy, but now he's been spending more time working, partying, and hanging out with his friends, leaving us with only about 2 to 3 hours a week together. I also feel like I have to fight tooth and nail just to get him to remember I exist. 

I'm trying to busy myself while I save up for nursing school by taking a medical training course and looking for work but for the past month, I've been left feeling very lonely. I'm not asking for much; just a night or two together and a call here or there to check in but, I initiate 90% of the contact. He's slowly let up on the cuddling and kissing and there's almost nothing left to his romantic side.

I honestly don't even feel like he's attracted to me anymore. whenever I bring this up, he tells me "I need to get out of my negative frame of mind" then shuts me down. Don't even know what to make of this...
<bot>: Boyfriend and I went from spending nearly every weeknight and weekend together to only sharing 2 -3 hours a week. Should I be concerned or do I give him his space?
