Unclear and confusing guy

Hmm, I think what your gut is saying about him, may be true given that he said he did not want to be a 'tag along'.

I think you should just ask him to meet up with you, or send a message saying - whenever you are ready to talk or meet, let me know, i'm here - it gives the guy freedom of choice and puts no pressure on him. Obviously, when he responds, don't be too available and jump at the first opportunity, suggest the next day or something - you get my drift?

Clubbing is probably not the best place for a meeting especially when with your friends, even if he did bring a mate along, it can get awkward, keep the two things separate for now. In my eyes, lunch or coffee would be more applicable, you can cut it short by saying you have a time restraint - lecture/uni/stuff to do and same for him. Given you at the same place, you could just explore the shops and stuff. Shopping and casual conversation.

Also, things change, when a person is on holiday they can be a different person to when they are at home so bear that in mind.

Yeah the thing is I don't want to seem too forward like I did that night he would have come clubbing but didn't, maybe I'll wait for a bit. I'm also worried he won't want to now after all that, considering he seemed off yesterday.
