Aquarius Men, is this an Aquarius thing or should I just make a run for it?

I met this guy on a dating app mid March. We met the first day we spoke & he said he felt something for me, he loved my honesty & he told me some really personal things to me (extremely personal things). I was a little taken back but I loved his honesty. He went away for a week but was always in contact with me. He texted me instead of me texting him. When he came back our relationship was official. For a month we were good. But after that month, for two weeks due to his job he only got one day off so I told him not to come see me because he had other things to do and his place was an hour drive. He told me he didn't want me to think I wasn't a priority because I was. But then he slowly started pulling away. The following week he gave me the reason he lives an hour drive away & it was to much just to meet for an hour. He been stressed with his job (works a demanding job - evening/night shift). He warned me in the beginning that his job gets crazy in the summer. He also suffers from allergies & has neck/shoulder pain due to his job. We mainly texted & calls were minimal because he works night & I work days. He didn't want to disturb my sleep. But when he called he basically was always in a bad mood & got upset with me.

Two weeks ago he said was stressed about work & he was being pessimistic. He needed space, he wants to be his positive & optimistic self. He told me he was still my boyfriend & wouldn't be talking to anyone else & we can still text to see how we are doing? He still didn't reach out to me but I did to him. I even text him if he wants when he is done from taking space if he wants to start over (we had a hit a few bumps). He said we will talk soon but it's been a week, nothing.

He acts friendly but I am afraid he is over me but he is just afraid to say it. Should I hold on a bit longer? How much longer? If not, should I say his silence gave me his answer & say my goodbye? or just leave it alone and not say anything and move on?
