God said forgive but there is a difference,if it a long term adultery forget about the woman,if done,caught and not caught but fact is there tell her.If she denies pray to God to protect you from her.One might forgive her that is you are no longer hurting and move on with your lives but if the hurt is still there just let her go.I tell you such a woman will turn arround and conspire to kill you.
Bottom line, you might forgive but trust is no longer there.The God we serve we serve him in truth and in trust.Remember thou shall have no other God besides me i.e though shall not cling to another man.Answer is get away from her if you no longer trust her and if she truthfully and honestly repent forgive.Long term adultery is as dangerous as keeping a poisonous snake in your trouser.

I dreamt that my wife of 20 years was naked in our house with a stranger,
I dreamt that my pastor was standing between me and my wife and holding our hands apart in his church and in the dream a one time member of the church was leaning on the wall looking at us.
I dreamt that i had a quarrel at the head office of our church but the quarrel was settled but on my way home i saw dogs attacking a horse galloping towards me and three dogs came to attack me, but i killed the dogs.
I dreamt that i was about to take bus when a mobile police man came pointing his gun at me to arrest me for rioting but i was not rioting, in the dream i was dressed well and don't look like involved in a riot.The police man took me to a dark ally instead of police station and asked me to remove my belt,something on the inside told me he was going to kill me over my belt.While in the ally i saw people looking down from above, i started fighting the police man and the people looking from above came down to beat the police like thief been beating in Lagos. His Gun was taken off him and i ran out of the ally calling him Ole.
If anyone can interpret this i will appreciate it.
