Please know that you are not alone. Perhaps your marriage is at a point where some outside assistance may be helpful in the healing process. Here are three recommended resources here in our diocese:
Contact your parish priest for a confidential meeting to help address your marital problems.
Catholic Family Services is available for marriage counseling.
Retrouvaille, a confidential weekend that offers hope and help for a couple to heal and renew their marriage relationship, is available the weekend of March 1-3, 2019 at the Broom Tree. Retrouvaille is a peer to peer ministry and has helped couples who experience chronic communication problems, as well as those who thought they were beyond hope, already separated, or even divorced. Please check the the website above for other regions if looking for a different date. For more information, or to register, contact (605) 988-3755.
