So this guy has been stealing my blind every orbit with these 3BB raises. He's limping a lot of hands from other positions. I've 3bet him twice, once light. He goes nowhere. I've called and donked. He goes nowhere. I want him to stop. This is my excuse for preflop and flop. Better lines? Keep folding?

Turn I pick up a double gutter plus flush draw. I lead (this was my plan regardless), and get raised, no FE. can I call?
