@Ceci693 Erm... Had a look at my phone to count just for a laugh, in the last 7 days, 12 guys. Not properly engaging with them all but that's inbound messages with some back and forth.
Not sure the mentality of having to choose one stranger to exclusively chat to without meeting them in suited to OLD. It's a little bit like being at a party or speed dating, you'll fleetingly bump into a few people, some you'll briefly chat to, 1-2 you might find more interesting. Unless you've at least gone on a date with one and really like them, and there's established mutual interest, it's just talking to a stranger online. What makes a stranger earn exclusive access to your time and headspace? Have they really done anything to deserve investment and commitment, bar a few text messages?
Imagine if you go one at the time, it might take 3-4 weeks to chat to them, go on a date and decide they aren't for you. That could result in a long hard slog online! Plus ley's be honest, most of these guys aren't even invested in as much as making a first date happen.
Personally I chat to as many guys I like up until the point I am properly catching feelings for someone and exclusively want to be with him. It happens quite naturally for me - e.g. if someone asks me out, and I'm taken by that special person, I just don't feel interested. So I know what my 'stop chatting to other guys' trigger is and usually that's a few dates and proper bonding time in, if not longer.
@Nosdacariad You seem convinced he's a wrong 'un... Would you be brave enough to cut him off?
