I went on a first date just over a week ago. He asked me for a second date & messaged me the next day to say what a lovely night he had. He told his friend he really liked me & wanted to go on another date. He's hardly messaged me since & made no effort to set up the second date. I messaged him yesterday to say i wasnt getting a good vibe & that if he wasnt interested then to let me know. He said we would meet after he came back from overseas. He goes away for 3 weeks as of tomorrow. Should i move on from him or am i being impatient?
