I met a guy at a club and he asked to dance together but I was nervous and decline. But then later I found out he's a friend of my friend's friend. We chat a little and I went back and add him on Facebook. Took him a week to accept and I send him a message. From there we chat. We will take a while to reply. The longest I waited was 2 days. I asked him why and he replied quickly that he was busy with his assignments. Each time he replies he will asks questions like he wants o continue the convo. After a week I asked his number indirectly and he gave me. Last night I whatsapp him saying it was easy to get his number. After a while he said good night and talk some other time as he has too much work to do. And then he joked guess u've been wanting my number all along? And we flirt a bit.
Is he being friendly or interested? Up till now he hasn't message me or anything. I don't know if I should initiate a convo again or wait for him? And if he doesn't should I move on?
