Should I contribute towards dates?

I’ve so far had 3 dates with this guy. He’s a single dad and I’m a single mom. When he dates me he pays for a restaurant meal for both of us, desert at a luxury desert parlour and then an activity after such as going to an arcade. He pays for all of that. Say diner, desert and activity in total would cost him £100 for the day. So in total he spent about £300 for the three dates

We’re gonna hit a fourth date which he said he’ll pay for

When I date him all he does is bad mouth his ex (daughters mother) saying how she cheated on him

We haven’t made anything exclusive. He just takes me out for meals and stuff and he has no intention of any sexual or any kind of relationship

I mean shall I pay for a few dates too or shall I leave it all for him to cover?
