Tough spot TD #3

[Seb86]

If you dont wanna read the HH here are the main fact : 1/2 on stars I get 23478 UTG I raise get 3bet by CO and I cap.

We are only 2 in the hand so I decide to stay pat. As a rule of thumb if we were 3 I would have drew. I am not sure if this is the right move though.

If I get raise on first or second draw should I draw ?
Was it a good bet on the river ?
