what to do when hes being confusing

Alright so we wgot together through text. We have nice convos... in person he was shy. I had to make the convo... but we cuddled and held hands. I dont know to me he seems off. Now after our first date he didnt text me. I texted him today. A day after... and he texted back but now i was left on read. Im in a relationship w him but idk what to do or say. I just dont want to seem needybut it also doesnt feel right
