Hey you're both consenting adults. If you tell your gf, it would be only to ease your conscience and that would be selfish of you and would hurt her. Ask yourself, who would you rather be with.
Little sis knows you're her sis's bf and obviously didn't care. She may have been using you to hurt her older sis. But now lil sis can blackmail you with this info, do you really want someone to have that kind of power over you.
Go after the mom next. What's to lose from here.
This is a very fucked up situation and I feel so bad for your girlfriend becuase you and her little sister are going to hurt her SO badly. But if you love her little sister then don't worsen the situation. Break up with your girlfriend and just date the sister before things get worse.
Don't make it harder on your girlfriend, just break up with her and don't fool around with her sister in teh mean time. Becuase then you'll hurt her worse and this stuation is already awful. And by the way, what you both did was so wrong.
If I was your girlriend I would have stopped talking to you and my little sister. You two would no longer be in my life. And that girl is a terrible little sister to your girlfriend and your a terrible boyfriend.
Karma's gonna be a *****.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
