Arrgghhh!! I am angry for you!! Why are they coming into your house anyway? You both should always be respectful in front of the child & when talking to him but who said you have to be friends? I don't know how old your son is but when mine was younger & his dad actually decided to see him, they didn't even come to the door & that worked better for all of us including my son. After he remarried, his wife always picked him up & brought him back. Please ignore me if you feel that is best for the child but after your son, your feelings are the most important in that group. Do what you need to so that the stress is at the lowest level possible for you & your son. Peaceful wishes.
