I'll try and keep this as simple as I can. My husband and I married several years ago. Both of us have children from previous marriages. We have a baby who is now 6 months. Half siblings love the baby. Before our baby arrived I made huge efforts to make sure my SIL, her husband and their children received presents at Christmas etc. I never received an acknowledgement. No thanks or anything. My texts to her were not replied to either.
Now I have had her brothers baby, she wants to have a relationship with the baby but I get ignored. I've spoken to my husband about it and he says she is selfish but loves her family and it's best not to say anything as it would cause huge damage.
In addition, the children's mother from my husband's first marriage is best friends with SIL. I have no problem with this but it is going to be odd bringing up my child who sees his Auntie 100% ignore his Mum but continue to be best friends with his half siblings Mum. SIL has even invited the ex wife to tea when my husband took his kids down to visit their auntie and I've not been able to go. He was not told she would be invited and asked her not to do it again. But since then she's had parties and invited everyone along. I just find this behaviour odd.
Do I just accept she will never acknowledge me and how do I explain this to my son as he grows up? I don't want to cause anyone any distress but am unsure how to deal with this odd behaviour. Thanks for listening.
