At the end of scene one, Act One, Troy declares his love for Rose. How is this declaration ironic?

Troy goes to Rose and tells Bono he loves her so much that it hurts him. He says he’s run out of ways to love her and that Bono shouldn’t come by his house on “Monday morning talking about time to go to work…’cause I’m still gonna be stroking!” This is ironic considering that Troy is a philanderer. I the beginning of act 1, Bono asks about a girl, Alberta, with whom Troy has been flirting, and reprimands him for not being completely faithful to his wife, Rose. Troy replies, “I eye all the women…Don’t never let nobody tell you Troy Maxson don’t eye the women.” Troy describes Alberta as “one of them Florida gals. They got some healthy women down there…Got a little bit of Indian in her.”
