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...
In my opinion infidelity is also a cowardly act, meaning your partner lacks courage.
Infidelity is also disrespectful making the perpetrator of subhuman.
I feel sad for you, you have been wronged, I do hope you escape from this experience a stronger person, you should do, in fact, I'm sure you will do.
