I'm going to lie to my girlfriend about abigail and lauren
Why are you going to lie to her about her friends abigail and lauren?
They keep talking bad about me
I know that you feel like abigail and lauren are talking behind your back, but lying to your gf will not help the situation. Be honest with all of them and straighten out the issue head-on.
I will admit that they are not to be trusted but I'll lie.
Well if you claim they are lying and then you lie to her she might not know who to believe. And you could just make everything a big mess and possibly break up.
