The 36-year-old actress - who recently announced her engagement to the art consultant - is enjoying having a stable life for the first time and is amazed at how comfortable she is having a "flat line".
She said in an interview conducted before her engagement: "He's lovely. He's very, very nice. It's really positive. I'm super happy.
"It's just the best! We go on group trips and spend holidays together - there's a lot of love! And that is really nice and very different from the way I grew up, which was more unstable and inconsistent, with a lot of highs and lows. It's funny, when I was younger, I used to say I'd hate a flat line - that I want the ups and the downs, the roller coaster. But I'm actually really enjoying the flat line."
Drew - who was married to bar owner Jeremy Thomas for a month in 1994 and comic Tom Green for five months from July 2001 - thinks she has finally found the right balance in her life now she has gotten older.
She told the new issue of America's InStyle magazine: "As I've gotten older, I've really wanted to find more balance and calm
"I'm pushing 40 and I feel like those things I always aspired to are finally being realised."
