What to say to a guy, when you ask him to be your boyfriend?
"Will you go out with me? I love you and care about you so much. " Then just talk about something random like a memory you have of them or something funny.
If a girl says "I'll give you ice cream everyday!" then that will win my heart.
Don't ask. You will look desperate. Wait for him to ask.
Tell him you really like him. Then if he replies back say we should date.
