Friend keeps obsessively texting/fb messaging! How to stop it?!?

[Happy]

Well erhm you have 2 options:
1. Tell him the truth, that he has to stop texting and fb chatting you consistently because it's annoying you, or
2. Lie to him, tell him that he has to stop texting you so much since it drains out your phone battery/ that you have limited texting and he needs to stop texting you so he does waste all your texts.Also, that he has to stop sending you so much messages on fb since it causes your laptop/computer to lag.
AND
If those 2 don't work, you'll have to resort to option.... 3 o.O (only do this if you don't mind him never talking to you and thinking you are a complete douche for the rest of his life)
-block his number, delete him from your contacts
-block him on fb
-ignore his existence (okay maybe not this one..)
