I have 2 daughters so don't know what it's like to have a Dil. However, as a Dil myself I know how it feels to have my children treated very differently to my SiL children by my MiL. When my D was born (1st grandchild to MiL and FiL) I truly wanted them to have a special relationship with her as I had done with my grandparents and made every effort to try to make this happen, even though we lived overseas a lot. I always invited them to every special occasion in the girls' lives and as often as we could in between times as I didn't want the distance to effect their relationship with the girls. However, my MiL has never wanted a relationship with them. She has always treated her D children very differently and has never had any time for our children. Recently my eldest daughter announced she was pregnant with our 1st grandchild (1st Greatgrandchild for MiL) which was a joy. MiL never phoned her up to congratulate her or send a card. In addition to this my second D got married last week and once again MiL never phoned to congratulate her, nor did she come to the wedding even though invited. When we asked her why she through a tirade of abuse at us accusing us of everything she could think of and saying that she resented her GD's because of this. This has been very distressing and my two daughters are both very upset that they were not contacted durng such special times in their lives. We have done nothing and have always tried to support MiL in every way, even though we have always lived a long distance away(sometimes overseas) so it's not always been easy to do so . I am not sure that I have ever heard of a GM do this to her grandchildren and I too am very hurt by this.
