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...
But, it seems like your H is committed to himself only.
If you give him a chance , you d really need him to accepting of having to earn your trust back and not on the easy side.
The issue for you at this point is whether you are willing to invest that time knowing the risk of failure, or cut your losses and be single and/or find someone you can trust.
There is a good book called, "Getting Past the Affair" that is quite comprehensive. We read it and can recommend it.
