Flopping Top 2 on a Flush Board

[cardsharkk04]

Party 10/20 5 handed, stacks are 2k. Raise up to 70 with Qc 10c in CO, Button (laggy) calls. Flop is Q 10 7 all hearts. I potted the flop and he bumped it up to 350. This could mean a lot of things. Top pair, a high heart, pair with a high heart kicker etc. I think for a bit and then reraise it up to 900, trying to protect my hand. He shoves. My action? Is it better to call his flop raise and check call a non heart turn? I hate this situation.
