Quote #4
"Did Mom know about all this?"
Henry felt the Ethel-shaped hole in his heart grow a little emptier, a little colder. He missed her terribly. "A little. But when I married your mother, I never looked back." (29.25-26)
The fact that Keiko was Henry's first love doesn't mean he loved Ethel any less. After he married Ethel, he was completely devoted to her—and he still misses his wife every day.
Quote #5
Henry had thought about Keiko off and on through the years—from a longing, to a quiet, somber acceptance, to sincerely wishing her the best, that she might be happy. That was when he realized that he did love her. More than what he'd felt all those years ago. He loved her enough to let her go—to not go dredging up the past. (33.23)
The fact that Henry hasn't sought out Keiko after all these years doesn't mean he gave up on loving her; he just loved her enough to let her move on and live out her own life.
Quote #6
After a few days, his mother did acknowledge his existence, in her own way. She did his laundry and packed him a lunch. But she did it with little ceremony, presumably so as to not go against the wishes of Henry's father, who had followed up on his threat to disown him figuratively, if not literally. (36.3)
Henry's mother doesn't stop loving her son when he's "disowned" by his father. Instead she finds little, invisible ways to take care of Henry. She still makes him lunch and does his laundry, though she doesn't talk to him directly.
