She wanted and she liked it! Otherwise would NOT keep sending the pictures! I'M, SO SORRY FOR YOU :( maybe she is scared of telling you that she doesn't love you anymore...or maybe you 2 don't spend time together?
Or argue a lot?....it could be a lot of things.... but the BASIC thing, to lead a woman to cheat....A good married woman a good wife? 1- REVENGE, 2- LACK OF ATTENTION(you IGNORING HER/no communication), 3 - sex! Lack of good PLEASURABLE SEX!
Specially if she was cheated first! Still I think you always have a choice, instead of cheating, if you wish to be free, you can always DIVORCE!
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.
