Biff ,  It is good that the two of you are in counseling , if you are going to try and make your marriage work .  Communication , loyality , respect and trust is the very foundation that a relationship stands on , they are the relationship .  Without these you have nothing . Something you said bothers me ...  "  I am working on the trust issue "  . I hope you mean your wife is also working on gaining your Trust back, trust is earned through our actions and behaviors .  The anxiety you feel when you are alone is a double edged sword ...  You have been betrayed  by your wife , you are hurt and you are angry ,this is not going to go away over night , and you do not trust your wife when she is out of your sight , also not going to go away over night .  I truly hope you find peace of mind and are able to hold your marriage together . Either way you are on the right track with counseling .  God Bless You & Your Family .
