Ex wants to take things slow with me :) advice on how to not be pushy?

Ok so ex was in a rebound and it’s ended!
He said he made a mistake and wants us to take things slowly, to see if we can get things back on track. He has agreed that the last relationship is dead but obvs doesn’t want to jump into it with me straight away.
Any advice on how to do this as I really want this to work?
And I don’t want to be pushy x

Don’t be too available to him. You guys are still not official so there’s no need to be there for him all the time - you have your life too. Don’t be needy or clingy because that will just push him away. You said he wants to take it slow, so just observe how he treats you or this relationship “slow” and just follow how does it. Don’t have sex if you guys aren’t official.
