Boy problem (commitment) ?

Should I believe him when he says he currently doesn’t have time to fully commit to a serious relationship? He’s not a fuckboy and doesn’t have many options. He also reassured me that he’s not meeting other women. In the very beginning he said he didn’t have enough feelings but now he’s changed his version after 3 months exclusively hooking up together and hanging out and having fun. He’s just really busy, doesn’t even have time for the gym, is quite insecure and we live 1 hour far away. He always replies fast to my texts though and engages, but recently he doesn’t initiate. He also gets jealous and inquisitive when one of us is away on vacation. Also, I’m his first casual relationship. Opinions?

Also, we always without a fault meet when I say so or when we make plans. He’s never cancelled so far.
