he needs space

So I've been seeing this guy for about 3-4 weeks now, he swept me off my feel, treated me like no other guy has treated me before, it actually felt like it was too good to be true but he reassured me otherwise, I've had no complaints up until yesterday and even then it's not a complaint, im just unsure of what to do. So in the beginning he'd call and message me regularly throughout the day but over he's been busy lately so we haven't talked much this week, in fact I have no idea what he's been upto, last I heard he resigned from his job as he hated it she has a new one lined up anyway but he doesn't start for another week. Anyway so last night we spoke and I just said that I feel left out and that I worry about him... he said he understands but he's just had a lot going on lately and needs his own space and hasn't been in the mood to talk to anyone. I've been giving him space and when I do he comes running back like 'babe I miss you so much, been thinking of you all day' as if I'm the one that needs space. How do I give him space but also be there for him? He hasn't been himself lately and I feel like he needs me even though he wants to be alone at the moment.
What I said/did was the exact same advice he gave my best friend when she had  a similar issue with her partner.
