Possible Flush

[Moutray]

Ok, I apologize for not giving all the chip stacks and such, but this is more of a theoretical situation. All involved have similar average stacks at a full table. THis is a $20 two table on Party. I'm on the button with AKo. Only caller so far is UTG. I raise 3xBB, small blind fold, big blind calls, UTG folds. Flop comes 10 K 3 all hearts. BB cheks, I bet half the pot. BB calls. Turn comes K spades. BB checks, I bet half the pot. Turn comes 5 clubs. BB moves all in with a bet of about half the pot. This would put me all in. Does this look like he had flopped the flush or was calling with a K thinking I was on a heart draw myself? And if he was so playing, with me betting the whole time, why would be not just check the river as well waiting for me to bet?
Thanks.

I would raise more pf. I would bet 3/4 pot on flop, check turn and call river probaly
