cs, the fact taht your husband picked up and left on purim when he saw his friends wife would not come out is a good sign. it shows that he values you over the friend. if you go there again ask your husband in a nice loving way to please be aware of the behavior and /or lack of friendliness toward you.
i get the feeling he will come around though it might take some time. if he is in business with the guy they can always do a business lunch or dinner on their own and not hae to do home visits. good luck.
dont yell, threaten or throw a tantrum..its gonna get better.
your hubby will see the light.
