There's a good Moyse book that went out of print for a time, bu I think it's back, after much public complaint. It's called
Tone Development Through Interpretation, and has a piano score if you want a friend to play along. They're mostly increasingly-obscure opera themes from the turn of the (last!) century, but still good material.
Maybe some pieces with
Music Minus One-type accompaniment recordings? This isn't the only available series anymore; check the Flute World website for MMO or
My Accompanist titles, with listings of the pieces each contains. They're a little expensive

(US $35 now, I think?) but nice to use if you aren't taking lessons, which is probably the best way to quickly improve musicality. The new Peters edition of the Bach sonatas has an accompaniment disc, though these are costly (worth it!) and are printed in two volumes of three sonatas each. Hal Leonard offers many play-along collections, though most are pop-oriented, also jazz and show tunes. These are less-expensive, around $15. Are there any community groups in which you could play? That might help, too. Glad you're back!

P.S. Also listen!! Listen to flutists, violinists, opera singers, you name it, for ideas about phrasing and general musicianship.
