bf sleeping habit

Boyfriend can only sleep well with me, it's fine but I do like my own space. Came back from 2 weeks away from him, and I really missed him. But we have only 2 months left before summer. Not sure if it's because I make him calm, but he needs to find ways of sleeping without me. Because within 2 weeks, he had less than 3 hours.

I'm just worried and not sure if it's temporary insomnia
