My Wife’s Affair Shattered (and Saved) Our Marriage

I'm inspired by this my wife just left me two weeks ago after 11 years of marriage and two children 8&2 years of age and she is seeing the next door neighbor frinds of ours I told her that i would fix the problem i guess we are not paying enough attention to each other . Now she seeking it else where with a man that prey on weak women not the first time he has done this to someone but not it is me looking on the outside looking in trying to fix what went wrong and being frustrated at the same time so when i do see her hateful words come out that i do not mean but that only making things worse i'm turning to god for guidance and prayer I do not want to give up on her even though she has cheated on me what should i do thanks dean
