Want to send as much love and support to you that is possible. Guilt is a powerful enemy of rational thought. It allows us to somehow discount facts and reality in favor of irrational fear and anxiety.
Its important to understand the basic tenets.
1. No cheating.
If you have an open discussion with your spouse that is no longer an issue
2. Loving and caring for your spouse
This is a big one and if you take the necessary steps and go through safety protocols, this will never be an issue. Love and support is love and support, so unless someone takes back that love and support, its always there
3. Not supposed to have sex with other people
Who said? Abraham had 2 women. His sons, Ishmael started Islam and Isaac was the first born of Judaism.
There are numerous accounts of sexual relationships between non married people.
