But you don't understand. He's lonely and she's prettier than girm number 2!

I agree. He's put no thought into her feelings. He simply doesn't have a right to approach her again after the stunt he pulled.

If a man broke up with me on valentines day to go fuck done other woman, he's be dead to me. And if he came back a tear later to ask to try again, I'd tell him to go fuck himself in the most explicit language.

He's probably the last man on earth that girl 1 wants to see again.
