For your own sake you need to reduce the anger as its unhealthy for you longterm.Sleeping with other women to hurt her is just toxic behaviour and will impact you more as it not behaviour you will be proud of.Its also deeply disrespectful to the other women.
It is always sad when a marriage ends especially if there are children but it can often be for the best.
My ex would have an entirely different perspective on why our marriage ended, its his reality so I have to accept it even if I don't agree with him.
I couldn't live with his anger and walked on eggshells, he however never agreed he was angry, just "frustrated".I guess he felt it was obvious.His anger came from childhood trauma.
Our separation feels unreasonable to him, however to me its liberation and I am happier although very sad that it had to end.
I had hoped to have an amicable divorce but his anger and bitterness has made it impossible.I can no longer feel safe talking with him so have to go NC.
This hurts the children and I wish it wasn't the case but nothing seems to calm him.
Please don't be like this, your anger will seep through even if you think its under control and the children will be aware.
You can have a good life again, it takes time to heal so treat it like a physical injury and be kind to yourself.
Focus on what your life will be like, take small steps to rebuild and over time the good days out number the bad ones.
If you feel bitter, stop and breathe, letting go of negative emotions and take in positive thoughts.
Youtube is excellent for ways to calm and soothe yourself.
Good luck
