If you no longer love him you should not pretend to, you should tell him NOW before Christmas.

Your boyfriend will enjoy ur love,, that should be enough for him
She wrote songs about her ex boyfriend the day after the break-up.
Yes
It is highly possible this young man is attracted to you and has been hoping you would break up with your boyfriend so don't be surprised if he asks you out. You made this young man's day by splitting up with your boyfriend and it shows he has good characteristics because he would not make a move towards you as long as your boyfriend was with you.
Have sex with him first then the day after that tell him you found a new guy and say i want to break up with you.
Yes, it is sweet to give your boyfriend a valentine.
i should give him a kiss and a love letter
if you mean your break during work then he might want to see you or brighten up your day or he's bored
You should carry on about your day regular. And when you call him later on act as if you missed him, whether you did or not.
No
That is entirely up to you. If you all can be friends than maybe you should break up and go together as friends. If you can't maintain your friendship then break up with him after the wedding to insure that your drama doesn't negatively effect your friends big day.
