Need advice on him not reaching out but always responds and picks up my phone calls?

I started dating someone 2 months ago and everything had gone really well he did mention to me he is an introvert and about 2 weeks ago he started a new travel job and since then he has really reached out. I know he is stressed but i brought to his attention last week asking if he felt we should still continue to date and if he felt he was too busy and he said no he felt we were fine! So i left it at that however i have mostly reached out and he always picks up my calls and always texts back but i went 3 days and he never reached out except he replied to my Instagram story thats it…i finally reached out yesterday he was like i haven’t heard from you…and i was like same it it always me and i left it at that! I mean i am not sure from a guy perspective would you just wait to see if he reaches out or bring it up or move on?
