Is he not over his ex?, am I a rebound?

I am seeing a guy that just been out of a long term relationship of 4 years and we ‘ve been seeing each other for 3 months.
I later found his youtube playlist with songs that seem to be dedicated to his ex and it has been updated with sad depressed songs about missing his ex and wishing he could turn back time to fix things. The playlist seem to be updated regularly even a day before going on a valentine date with me giving me roses etc.. And a few days after our date he was adding sad depressing songs about past relationship and missing his ex still.


Is this a red flag , Is he not over his ex? am I a rebound?
