Be VERY careful how you behave for if you do something stupid, your ex-wife may use it to seek a protection order against you and THAT would not be beneficial for you nor your son in any way, shape or form. But do continually ask your son how the OM treats him - does he yell at him, hits or pushes him, says hurtful things to him about you, etc. - for that is your duty as a father. The total well being of your son is all the matters.
Consider also that your actions against the OM may have contributed to your ex-wife wanting to continue her relationship with him. You may have inadvertently served as a uniting force and extended their relationship beyond the point of existence. So butt out and let them be.
