He said: “My biggest investment is my family.
“I’m with the person I’m supposed to be with – I’m not looking for anything else beyond Eva – and I feel very lucky that we have a beautiful, healthy daughter, who is an angel. That’s investment enough for me.”
The actor is unsure whether he’s a good dad, but he tries to be around as much as possible.
Asked how he fares as a dad, he said: “You’d have to ask my girlfriend really – all I can say is that it’s important for me to be there for my daughter and that I want to be there too, because it’s so fun.
“Being a dad isn’t rocket science – I can handle it.”
While he is devoted to his family, Ryan, 35, insists he and Eva, 41, aren’t in a rush to have more children.
He told HELLO! magazine: “Just one step at a time please.”
