Hi all
Long time poster, but gone anon for my modesty

So I met a guy online about 2 months ago - we hit if off immediately on the first date both from a personality and physical sense. Now here is me going into paranoid mode - I just feel that he is either taking it super slow, or is maybe just stringing me along?
We have had 5 - 6 dates in this period of time, and all have been terrific (I have stayed over with him etc etc). We get on really well, and it is so relaxed and normal etc. However, I am used to being in a relationship where we are in more contact, seem to be more interested in hearing about each others lives, spending more time together basically! Like the last 2 weeks have gone by, and I have not seen him - yes, we text frequently every day, but we don't talk on the phone (we never have, and to be honest, I am not really a phone call type of person!!!!).
We work very close to each other, and I even suggested we meet for a coffee or lunch some day, but he has said he prefers after work....
He has a very high pressurised job and kids from a previous relationship, so I know that he is flat out with all those committments!
On the other hand, I have been in relationships where everything went at rollercoaster speed initially, and they were all failures!!!!
Am I just being paranoid here? I really like him, and don't want to do anything that could jeoparidise anything!
