Ok, nobody loses their temper please.
For this statement:
"After losing once to Team Rocket, he learns Green is in love with him and has been since the battle with Mask of Ice." (Green here refers to the girl named Blue in Japanese)
is completely false and made up. There aren't really any substantial hints of love between the two (unless you count their early encounters in RGB where Blue (Green) calls Red her sweetheart in front of TR).
This other statement in the last paragraph of that wiki page:
"During the battle, Green confesses that she loves Red, which is why she sent Yellow to save him years ago, which was the time when she discovered her feelings."
is false as well, reason being the same as above. The author of this sentence might have mistaken the discussion between Red and Blue on Five Island as a love confession, but actually it was more about Blue encouraging Red as an old friend, and her voicing of her desire to participate in the battle against Deoxys.
