Ask your wife for time to speak. This should be at a time when the two of you have a break from difficult work responsibilities and family obligations.

Explain your feelings about the marriage to your wife. Be as specific as possible about what you are feeling. For example, if you feel the passion has left your relationship, say that, rather than saying, "Things are different now." Allow her time to communicate her thoughts on the relationship as well.

Tell her that you want to separate. Give her the reasons you want to separate rather than trying to work out your issues. If you want to find true love or if you do not love your wife any longer, give those reasons for your decision to separate. Be clear that working things out is not an option for you, if you are absolutely sure you no longer want the marriage.

Explain to her your wishes for the two of you. Tell her that you will make the effort to be there for the children and will try to make the separation as easy as possible by respecting any boundaries she wishes to establish.
