This is a tricky one… You do get a lot of the old “cold feet” but if you’re getting a lot, it sounds like either really bad luck or something needs fine-tuning in your approach.
I’ve always favoured a very direct and decisive approach from the offset, which I think defines the way everything plays out. I think a bit of assertiveness works well as most women are a bit dithery about meeting – they don’t need much of an excuse to back out.
So rather than the sort of “I’m free Wednesday… If you’re not doing anything… and if you fancy meeting…” approach, I always go for more of a “I’m free Wednesday, so why don’t you meet me in [insert town/bar] and I can buy you a drink”.
I’d always suggest the lady chose the actual venue so she’s more comfortable (“somewhere public and well-lit, plenty of fire escapes in case either of us needs to do a runner”) but apart from that, I try to “grasp the nettle”.
I know the haterz will say this sounds arrogant and misogynistic, but it always yielded better results for me.
