Pav insecure/immature. Absolutely no need for any of that and I can categorically state it was about him, not you 
Biddy I rather like a "salt and pepper" of men my age at gigs
. Bant a "parliament" is too suity (and Tory) for me.
How about a "Garvey" low growling sound or a "Hyde" (Karl. Massive crush) or a " insert the musician of your choosing " that can change at will/hormonal status.
I went to a gig a few years ago full to bursting with late 40s indie/ex-raver/silver haired/interesting eyewear types and actually said to my friend "aaaaah, I am amongst my people"
All ignore the "no"s or the probability is you'll waste a lot of emotional energy on explanations/getting involved in other people's (people you know you will never meet's) issues.
I know I bang on about manners, but there I mean once some kind of communication has begun. Not having replies to messages is just a part of OLD for both sexes; it's the easiest option. Starting a dialogue that you know won't end in a date is crueller (dont mean cruel, really, but can't think of a better word) IMO. Plus as mentioned, it can then mean you get sucked into something that has nothing to do with you and everything to do with the other person's psyche.
Polar sounds great 
If he says he's not sleeping with anyone else then why isn't that exclusive? Surely that says he IS ready??
Wingle he's not necessarily messaging/actively looking to see someone else, just could be reading messages that have come to him etc etc blah blah. And I agree with Pav in that a week isn't long at all.
I have to say one of the things I love about Bumble (and there's a few, surprisingly) is that you have no idea when messages are read and whether the other party is online or not. I welcome that.
