You knew this would hurt me, and did it anyway

Yup.
You knew.
You knew it was wrong, and you knew it would hurt me. I feel like its hurt me beyond repair. I wont trust again. I dont want any new female friends, cause id never trust them around my man. Apparently, the only women i can trust round my man are the ones ive know forever and ever. And i cant get a new "since forever" girlfriend.

Both A and D tried to hide it from me. They told other people before they told me. They never told me, my best friend couldnt stand seeing me, talking to me, knowing what was going on, knowing that i didnt know. So she told me. And she did the right thing. D, i dont care that you are angry with her, she did the right thing.
Both A and D have, since this bomb dropped, made it clear that they think it would have been better if i didnt know they were together. How could i not know? D told more than one of my closest friends. He even told a friend that I introduced to him, someone who is MY friend first, not HIS. What the hell were you thinking???
