Yes, and without reservation. Apologies to her boyfriend, (for I haven't heard that she married him,) I don't think she finds her life as interesting without tennis. Also, since doubles complements one's singles game, by playing singles, she would be getting in more practice for her doubles...whether or not she "succeeds" at either.
Remember Bjorn Borg? He made three comeback attempts.
Gotta go with what you know.
