Update

So, as previously mentioned, I have acquired DB's number. I sent him a message after 2 days of hassle (mostly from one of my married friends. B. who has text me almost non-stop, and another married friend. H. Marrieds, eh?). And he replied and he said he was going to a gig of our mutual friend (this was the spurious reason I gave for texting him) and he ended with 'see you there, I hope'. And you know what? That's OK. I haven't over-analysed the shit out of it. It is what it is, I will see him on Wednesday and until then I shan't obsess. Promise.
