But that doesn’t mean she isn’t open to finding love again. Aniston, 50, toldHarpers Bazaarin May, “When [love] comes knocking, it’s going to be welcomed. I’m not like, ‘No, I’m done with that.’ ” And a source adds it’s only a matter of time before she finds that special someone.

“She will be cautious [about dating again]. If something comes into her life, that’s fine, but she is not sitting on the edge of her seat,” says the source.

“It’s not because she doesn’t want to [date], but because there just hasn’t been time for her to focus on it,” says an insider.
