MY LOGIC:

I was happy with the PF call - it was only a minraise and I was pretty sure that BB would complete and UTG+1 would call making it a five way pot. $.75 to win $5? I'd do that with a lot of things. And these were soooted!

The flop: I'm not sure about whether calling was a good move. Although the flop was pretty good, it was not perfect and there were players left to act behind me who could have raised. Even though nobody did, I was still calling a pot-sized bet on a draw to only the third best flush or a gutshot draw to a straight or straight flush. I'm beat now and I might not even be drawing to the best hand.

Did I have enough outs and were the outs strong enough to call this bet with people behind me?

The turn: I was hoping the Ace would be a scare card and making a smallish bet would at best win the pot for me there or if he calls, it's a fairly inexpensive way to see the river after I picked up a couple more outs.

I probably would have folded to a push but he only minraised it so I felt I almost had to call at this point.

The river: I made my flush which gave me the second nuts. I felt that villain, having invested so much into this pot, would call my bet that put him all-in with worse hands than me (I thought he had two pairs or maybe a straight). Since I would have called an all-in and paid off the Ace-high flush, I felt that betting what villain had in front of him was the best move.

How's my line?
