I have 2 nieces who are grown and are adults now. I just had my birthday and they did not call me, email me or communicate with me via facebook to wish me a happy birthday. I heard nothing from them. They always wished me a happy birthday prior to this. I do not believe that they were too busy as they were all over their FB pages posting stuff and other family members told them of my birthday so I do not believe they forgot. The reason I think they ignored my birthday is because their mother and I had words over an incident that occurred while we were visiting them 2 months ago. Their mother is a very controlling person and a bully. She insulted me and I did not stand for it. I defended myself and she did not like it and is now giving me the silent treatment as some kind of punishment. I believe she told her daughters to not have any contact with me and thus they ignored my birthday. I was thinking about no longer using social media to interact with my nieces since they ignore me now. I was going to eliminate both of them as contacts on my list. My question is, am I being petty by doing this? or should I just go ahead and cease communication by social media since they don't care to talk to me anymore?
