So my sister seems to have some issue with me around me not initiating weekend plans with her. She's a single mother of a 5 year old son she had from a donor. My nephew loves my 7 year old son and often wants to spend time with him, so my sister would often initiate weekend plans with us. In some way, I always felt like it was mostly to entertain her son as she would barely communicate with me during the week.
In November she decided to have a fight with me because I wasn't available to do some activity with them (I had plans and she was upset that I didn't want to cancel my plans to see our elderly mom and/or didn't notify her that I was going to visit mom). Basically it was just a manifestation of some deep issue she has. After our facebook exchange, she blocked me there.
I saw her beginning of Dec for her son's birthday. She tried to act like nothing happened. I didn't allow this as I'm tired of her tantrums and ungreatfulness (I have helped her several times including when she was sick, invited her to my cottage, etc). She decided to mirror my coldness.
Next day was my birthday, she came with her son, barely uttered Happy birthday (supposedly because I didn't congratulate her with her son's birthday eventhough I came to the party for him!), didn't have a gift, sat on the sofa with her phone while I was setting the table, didn't control her son who was throwing my son's toys everywhere, didn't help even to put some plates to the sink...About our issue said that I, as usual, don't understand her. Nothing more.
Never unblocked me on Facebook, but wrote to me on WhatsUp when she needed my help for something.
I don't feel like inviting her to our house for Xmas, but I will invite my mom so she will know most probably. AIBU?
