I recently meet a guy online, and we got on quiet well. I initiated and asked him whether he wanted to talk on the phone or meet up sometimes and he was agreeable. He gave me his number and asked me to text him. So I texted him. I didn't say a lot in the text - just a brief text and ended there. He called me back that night and we talked for a long time. Since then he has been calling me once every 2 nights at least. I am pretty cool and don't demand a lot of his time as I have a pretty busy life myself. Sometimes I would call it a night on the phone when its getting late or I would ask him whether he needed to get off. He haven't called for more than a week, and I'm just wondering whether I should give him a ring or move on. I have to say I feel that sometimes I might not be the most affectionate person, and I don't want him to think that I am not interested, but at the same time I don't want to seem too needy. I sometimes wonder whether I am too much or simply too less?
What are your suggestions?

Call him. Tell him you've missed talking with him. (Don't demand an explanation of where he's been or what he's been doing.) By the second or third sentence, you should have a good idea of where you are in his thoughts.

So many "ifs" but call him, but remember
1. you meet online
2. have only talked for a short time on the phone

You can not be sure if perhaps his wife came home or he traveled and is home for a week or something.
I know the first lady I meet online turned out to be married and just wanted a fling.

But at this point just call and talk

One week of no contact won't qualify you as needy, that's for sure!

If you're interested, then take the initiative to contact him. He might think that you're not interested because you haven't called him either.

Either way, there's no way to know what's going on in his mind until you get in touch.
