Hero ($50) opens CO $1.50 with ThTs
SB ($50) raise $5.50
Flop 7h 2h Ah ($12.25)
SB bets $4.50 hero calls
Turn Jh ($21.25)
SB bets $14.50 hero calls
River 7d ($50.25)
SB jams $25 Hero folds

Now I'm assuming I'm supposed to be calling river. But I folded since I assumed perceived fold equity was quite low once I call turn.
I'm now thinking with the pot odds I'm should have just called. What do you think?
Villain is a fairly aggressive reular, which leans me more towards thinking I made a mistake.

Thanks
