I’m not understanding the reasoning?

Hooked up with a man out of state 6 months ago that I was previously talking to off and on while on vacation. The night was very intense almost like love making. Offered to pay for my stay and reinsurance me for my time off of work if I stayed a extra day… yet I left cause the trip wasn’t for him and I had to get back to work.

Make a long story short nothing came out of it yet we still talked off and on despite me living out of state. He’s very inconsistent yet possessive? I went out of state for my birthday and he was asking what man paid for my room, if I was with a ball player or rapper? He also went to my page every day despite us not following each other and watched and hearted my stories?

Fast forward a couple weeks later he was ignoring me and my texts yet texted me the night two hours before his birthday? I never responded a month and a half past go by of off not talking, I follow him he followed me right back then called me. Asked me why I never wished him a happy birthday months ago? I had to get off the phone and he demanded that I told him where I was going and who I was going to be with…?

Told him I was going to make food, he then told me to send a picture of the food afterwards to him just to make sure that was what I was doing? He’s inconsistent and said he doesn’t want anything with me, so why is he behaving like this?
