A counsellor is a very good idea when an affair is going on... but the counsellor must put the marriage first and affairs last.

As long as the counsellor is NOT going to support an affair in any way its a good thing.

People in affairs or considering them NEED people to talk to as well... shutting them out just gives them little alternative than to stray or to continue straying...

I don't think counsellors should EVER endorse or support an affair, I don't think they should turn people having them AWAY either.. the counsellors here certainly don't.
