The former Breaking Bad star, 30, has been dating Geraghty since last year (11) and she insists their relationship status is perfect as it is.
Ritter tells Playboy magazine, "I was never the little girl who dreamed about a wedding or a big white dress. I don't think I'm sour on marriage. I just don't know if I'm the type.
"Marriage seems scary to me. I'm in a serious relationship. We have a dog together. We live five minutes from each other. It's heaven. I think that might be the key: separate houses, separate bank accounts. Why mess with that?"
