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...
Mourn the loss of what you thought you had and move on.
This is all a reflection of who he is and not you.
Do not be thinking that he will change and all will be well. It doesn't work that way. This is who he is. He is a liar and a cheat. Block him and cut
him out of your life.
You could talk to a therapist who might explain all this to you. Most of
these cheaters are narcissists. Read up on them. Take it slow, but get back into your life.
Good luck to you.
Imagine being married a decade with kids and then finding out......many of us here are in that boat. We would all wish we had found out the true nature of our spouses back before we married them.
Whatever you do, don't even consider taking him back. He never had the intention of being faithful even BEFORE he was to marry you.
If you do let him back in and marry him you will be in a worse situation that most of us are in and will look back and wonder why you ever took him back. Then you will feel infinitely more regret and loss of time.
