My finace was previously married and was extremely close with his ex inlaws (parents and siblings). Although he doesnt keep in close contact with them, he has remained friends, i.e. stops to talk to them when we see them out and about. His divorce from his ex was brought on due to her infidelity, so her family has no hard feelings with him, however, his ex is less than cordial to me, thus her family acts as though i dont exsist, but is not rude to me. One of his ex brothers in law is still one of his best friends and is traveling here just for the wedding. We are not sure if we should invite all of his ex inlaws so that they do not feel as though we are isolating them, but at the same time we dont know if it is appropriate. We live in a very small town (6,000 people) and dont want this to get ugly. But we just arent sure what to do. In essence we would be inviting all of the family except his ex wife.....I dont want to be in the middle of a bad Jerry Springer episode on my wedding day, but dont want my fiance to worry about offending people that have been apart of his life for nearly 20 years.
