Text ex girlfriend happy new years? Still love her :-/

I was wondering how it would look if I at least texted my ex with a simply happy new years and wished her a wonderful year. Would her ego think I'm still chasing her and make matters worst? Or would it show her that I was obviously thinking of her and wanted to be polite. Ultimately by showing I still care backfire or is it better to just continue to ignore. I miss her a lot and I know she still has feelings or else she wouldn't have flipped out at a week ago when she saw me dancing with another girl at a bar. Its been 6 months since we last talked.
