So I met this guy online, and have been chatting since (about 2 weeks). We have heaps in common, and have been having a good laugh together. He straight away asked me to go for a drink with him. Arranged for the Sunday afternoon. He cancelled this date claiming he had a meeting with someone from work and re-arranged for Tuesday. Ever since this, he has been really distant and not initiating conversation. Then, on Monday night, he cancelled Tuesday'a date as he needs to work due to a colleague being unwell. I told him not to worry about it which he hasn't replied to. Should I take it that he isn't interested in me anymore? I just don't understand how someone can change their mind so quickly?
