My brother in law called my husband a fake ass dad because we are foster parents (due to having 6 years of a infertility battle) My husband hide him saying that from me for over a year. When my husband told me it ate away at me. I ended up put a post on Facebook not saying anyone’s names or any specifics just stating that. “I hope your wife never feels that pain… I hope you get the gift of having a biological family.” Well brother in law sees the nonchalant post and his wife texts me that I am a horrible person I cause drama and states that I SHOULD have put names in the post and SHOULD have tagged them. We removed them from our life do to how they have treated us. Fast forward 1 month brother in law announces they are expecting. He calls my husband and says “we need to fix our issue’s because you need to be in my child’s life” my husband responds congratulations and they haven’t spoke since. Baby was born we were never invited to anything. We have not seen the baby nor spoke to them… I guess my question is AITA- for not saying congratulations or sending a gift or attempting to be in the babies life. I have plans to send gifts to baby at Halloween and Christmas for birthdays etc… but should I!??
