Can I get a restraining order against a cheating wife having contact with her affair partner?

You can not lock her out of the house, change the locks or pack her bags. You can not use the law as leverage to make her abide by agreements of faithfulness made in counseling. If you try, you will complicate your situation and compromise your standing in any legal actions that may follow. What you need to do is quietly examine what you want out of your relationship with your wife and the possibility of achieving it. If you BOTH want to save the relationship then continue counseling and try to regain some trust in each other. You can not return to the relationship you once had by controlling her every behavior, particularly in the workplace. It does sound to me that you are making this her fault — but perhaps you should examine what caused her to stray. You should also know that 75% of people ending their marriage because of infidelity regret it within 5 years. If you don’t think the relationship is salvageable, then you need to accept it and move on (not easy) and see a divorce attorney. But, the worst thing you can do is bring the hurt anger into the divorce action. The Probate and Family Court will settle the matter on objective grounds unencumbered by the subjective motives of the litigants. The anger will color your perspective and dramatically increase the costs and longevity of the divorce. The last thing you need — should you decide to divorce — is to needlessly prolong the misery.

I am so sorry that you are going through this. As my collegue so properly stated you have to be careful that you don't break the law even though your heart is breaking. File an action in court, name the spouse as an adulter and embarass him that way if you need to. Good luck and take care.

Do exactly what my two great colleagues suggested, but also keep in mind the best interests of the children. While your wife may no longer want to be with you, you and your wife will have do your best to co-parent effectively so that the children will be much happier and will not feel like they are caught in the middle between two people that they love. Drama and ugly incidents can have very unhealthy effects on the children. Given your facts, there are two bad scenarios that may result. Either the police will show up when your wife calls them when she discovers that she has wrongfully been locked out or your wife will be pounding on the door and you will be in the awkward position of instructing your children to ignore the cries of their mother. Cheating is a symptom of a bad marriage. Unless you honestly believe that you can change her ways and/or create a happier marriage, I think that you deserve better and should seek a divorce.
