Perfect contact. The A hit his range hard. If he wasn't jamming with the flush it was with the A or K of flush and we're now even further behind his range. The A is a devastating card. Given that you called the turn the river is a must call. I almost want to raise but not quite. if they were slightly more agg I think you can raise since you're now representing a big enough hand so that you can safely fold to a 3bet. He'll likely just call you with almost every flush.
