I'm so confused and frustrated!

Hey everyone :) I met a guy last week and we went on a date the next day (Saturday). it was an extremely pleasant date and we appeared to click. He sent me a text asking if I got home safe, I replied saying I did and that I enjoyed his company and would like to meet again etc. He agreed and was very eager to fix up another date, I offered the following weekend but he said he would like to do a weeknight if possible. We fixed up a date for Tuesday, but he warned me he wouldn't know what time because of work and asked to play it by ear. Tuesday afternoon he text apologising and saying he would be very late home and could I do Saturday, which I agreed to. Since then he has sent me two short texts and nothing else. I don't want to bother him by keep texting if he's busy but I just want to know where I am. If he's not interested then I wish he would just say! Initially he seemed more keen than me, now I feel all needy and frustrated! I sent him a message earlier which still says 'sending' ... I know his signal isn't great at work but I don't know if its a technical error or him being quiet! What do you think guys? Should I leave it until tomorrow and text asking if we are still on for Saturday?

Why be frustrated? Leave it to him to organise your next date. You obviously are very keen but the ball's in his court at the moment. If he wants to take it further, he will. Watch his actions and not so much his words and text messages.

Thanks everyone :) You were of course totally right and we had a fantastic time today :) thank you so much for the replies xx
