My son and his wife are having a baby in April. His Father and I have not been together for over 25 yrs, he is married with a teen age son of his own. I am throwing a baby shower for my daughter in law and the baby. I did invite my sons Grandma and Aunts on his Dads side of the family, because we have always remained friends. I did not invite his Dads wife because she is not a very nice person. Well his Dad called my son up asking why his wife wasn't invited so now my son feels stuck in the middle, and is asking me to invite her. I feel this is my shower for my family and people I decide to invite and I don't want to invite her, it is too awkward. But I told my son if he really wanted me too do it I would. HELP!
