@unknownDB,
You're right; the fake FB account was stupid. Close it immediately and come clean with your boyfriend about it. He
might forgive you. Personally, I hope he doesn't. It showed some serious immaturity and a lack of trust. So, you may be asking, why would you tell him if I am saying it should end in ashes?
Because -
* you'll get a lesson out of this
* you give him power over whether he wants to continue and forgive you (I don't normally condone giving up power, but this was a really boneheaded move on your part)
* you will at least clear your conscience before you do any more damage
And will you learn,
please, that creating entrapment situations for nice people who care about you is not only stupid, it's hard on the aggressive side of passive-aggressive behaviors?
