I'm not much of a regular, but I've name changed for this as a couple of RL friends know my nickname on here, and I'm not ready to tell them about all this yet.
Basically my dp of 10 years has been having an affair with a friend of mine. Its the third time he's done this now (I know I'm stupid for staying with him - I wont be doing this time, three strikes and you're out and all that), but anyway, I do blame him much more than her, as it seems this is the kind of person he is.
Despite that though, I'm still really angry with her, when we're friends. She knows we have two young dc and she knows he's done this before, and that another time would be the final nail in the coffin.
Part of me wants her to suffer for what she's done, and I want to contact her dp (they have no children) to tell him about it (i have evidence in the form of fairly explicit emails between the two of them), but then another part of me thinks this is just revenge, and I shouldn't stoop so low.
Would it be wrong to tell him, and should I just concentrate on getting on with my own life and getting over it myself, or should she have her life ripped apart in the same manner.
