I have a 35 year old step daughter, have been married to her dad for 3 years, he was divorced 3 years prior to our marriage. Despite including her in the wedding and inviting her to our home,etc. she has continued to ignore the fact that I exist by sending holiday cards etc. to her father only or to "(last name) residence" on the envelope. I have never been spoken to on the phone or inquired about during a conversion with her dad.
