According to Romeo’s parents, how has Romeo been spending his days before meeting Juliet?

According to Romeo's father, Romeo spends his time alone in his room, crying over Rosaline.

Many a morning hath he there been seen,
With tears augmenting the fresh morning dew.
Adding to clouds more clouds with his deep sighs;
But all so soon as the all-cheering sun
Should in the furthest east begin to draw
The shady curtains from Aurora's bed,
Away from the light steals home my heavy son,
And private in his chamber pens himself,
Shuts up his windows, locks far daylight out
And makes himself an artificial night:
Black and portentous must this humour prove,
Unless good counsel may the cause remove.
