I have caught my wife cheating on me with the same guy 4 times in 2 years. I have never cheated on her or lied to her and I have forgiven her each time. I have just decided I am done but I want to be smart. I told her that we can stay together and work on our marriage but I can't take it anymore.

I want to be smart. I want to do everything I can to get prepared before letting her know that I want to end it. I would like to put monitoring software on her phone so I can get evidence to support my case but I don't know what to use or if I will be able to install. She has an iPhone 6s with up to date software. I have the apple ID and password.

I would really appreciate advice on what I can do now to get prepared for the divorce before she is aware it is coming. She just quit her job and has worked our entire marriage. She will want my kids but I don't want to give them to her. She won't be able to handle them. I work full time and will be able to show that I have the family structure to help me take care of them.

I can not forgive her just to see it happen again. I can't do it. I have to end it. I have given this marriage every chance. I think I deserve to get out of it with my kids and my finances. Can anyone help me figure out how to do it?
