Infidelity Support Group
Any relationship in which one partner engages willfully in sexual relations with another outside of the partnership is considered to have experienced infidelity. This breach of trust is often traumatizing for the faithful partner as well as the relationship, and support is often needed to heal emotionally and to decide whether or not the relationship should continue after...
Are you feeling bad because you were cheating or because you got caught?
It sounds like she has moved on already, and that should be an indication that you should too. There was something missing for you in the marriage that created this situation. Could that be worked on? Maybe, but can you see being with someone that will NEVER trust you again? I believe that trust can be re-built, but the relationship will never be the same. If you both are ok with that then there may be a chance. If not then time to move forward.
Don't put your child in the middle of this at all though. They do not deserve it.
