Short dates. Dragging dates out for hours rushes intimacy so keep dates to around 2 hours or under. Occasional 3 is fine.
No sleeping together (though I bet my ass that isn't what he meant) until there's been another chat to suggest he's all-in.
No labeling things (which I'd bet might be whats he's actually after).
See eachother just once or twice per week.
No constant texting ect...between dates.
Revisiting conversation about where we are both at in around 2-4 months time.
That would be my idea of taking it slow.
Just be careful of anyone who gives you a sob story about their ex leaving them 3 years ago and them still being all sad about it and it being a reason to fanny you about. It's not.
Taking things slow is fine. So long as he a. Doesn't want all the perks of a relationship, without the commitments. And b. Doesn't start fannying you about with all that 'I don't know what you want right now' shite. Because I ge does, he's taking the piss.
And if he isn't over a bad break up, he shouldn't be dating at all anyway.
