Should i innitiate the 4th date?

im a guy whos been on three dates with this guy. we get along pretty well when we are together and there is certain amount of chemistry. on the first date we both agreed we would like to meet for a second. we did and that went good too. a couple days later he asked me if i wanted a third date. i did so we went out last weekend. again it went well. the thing is he isnt that forthcoming with texts or overly forthcoming inimitately when were alone.

i am usualy the one who asks him first how his day is going. i havent spoken to him since i left his place on sun, he was apparently ill when i last saw him. i changed my facebook photo today and he liked it, so i guess that means he still likes me lol of some sort do u think? im certainly not the type to chase guys i dont need to beg for a date and not needy at all. however i still use plenty of fish and i know he does because ive seen him online while i am on there too..

as he asked fora third date should i ask for the 4th. i am very fond of him so i guess i have nothing to lose. its just i dont want to waste my time...

what should i do?
