I was meant to go to his place today but because he had to think about it before deciding if I should come ot not, I sent him a text to say thay: "dont worry, i will not be coming to ur place today because i have got an important place to go and i dont know when am going to be available and when i am, i will let you know". Do you think that is a good idea because I believe he his just playing with me and I need to let him know that 2 can play that game.

No. It is a horrible immature idea. How fun is it to just keep going back and forth and back and forth.. none at all. One of you has to step up and take charge. The relationship will go no where and end up in shambles.
