"It's me this week! They got you in your tracksuit, did they?" Ritchie joked about their conversations.
The mum-of-one also said she'd consider having more children, saying she'd like to give her three-year-old daughter Mae more "little people" to look after.
"Having children is a wonderful distraction from yourself, and also opens up a brand-new
world that is far greater than anything," she said.
This year marks 30 years since Ritchie debuted on long-running Channel Seven series Home & Away. She starred as Sally Fletcher in the soap for 20 years before leaving Summer Bay in 2008.
Reflecting on leaving the character behind, Ritchie said she felt like "something had been ripped from me".
"As long as I can remember, Sally Fletcher brought so many wonderful things to my life.
People wanted to meet me because of Sally, or I won awards because of Sally, or I was invited to great events because of Sally," she said.
"When you don't remember your life without it and all of a sudden that doesn't exist, you wonder, 'What is it about me that is attractive?' It's been a very long process of trying to work that out — it was about finding my own identity. And what I realised is, 'No, Kate brought wonderful things to my life.' I had to finally realise Sally was a result of me, not the other way around.
"I felt as though something had been ripped from me, like that security blanket. Maybe I
never really realised the joy I got from being someone else."
Ritchie, who is currently part of Nova's hit national drive radio show Kate, Tim & Marty, said she has not turned her back on acting and "would jump at the right gig tomorrow".
