what do you think?

Right so I've been talking to this guy and have slept with him a couple of times and been on a few dates. He has told me that he does like and is interested in me. However on Thursday he cancelled a date due to fair circumstances and said he'll re arrange for next week but yet there has been no mention of the date again? When we are out down the pub or whatever he is only flirting with me etc. However recently he never makes any first point of contact it's always me but he replies fine and it all seems like normal. I have really began to like this guy so I really am unsure on what to do .... wether I should give up and stop talking to the guy or continue how it is and see if it progresses. I would really appreciate some advice and also what you guys would do!!! I am 19 btw and he is 20.
