I hve found my wife having affair one year with her friend and i have my daughter 4 yo i wnat divorce her ?

Give her divorce immediately as soon as possible, Make your bed separate from her, don't sleep together with he in 1 room, I think you can apply for divorce, you have A very strong reason to divorce her, take all her email correspondence copy's, and save it to other email address or forward it to other email address, or save it in any hard disk, and save her nude pictures too, She has committed adultery, and it A dishonesty with husband, Don't give her 2nd chance because her soul has corrupted, about your child? whatever the court decides, that's all, this is your destiny you have to face it, that's what i can say!!!
