He still interest or not?

I met this guy on online dating and we have good conversation then. We always chat almost everyday and do video call since we live in different country. But, he suddenly missing without news. I texted him but no reply. After 2 weeks, he texted me said that he's busy and there are problem with his Skype account. So, we change our communicate tools by use messenger. At first we had good chat and conversation again. Usually he text me then we do like video call. But, lately he never text me first as usual. I always text him first. He always reply fast when i texted him. I'm scared that i'll look clingy to him although he ever say that he like me to text him first. Is he still have interest on me? should i continue to text him first?
