I didn't invite my friend's daughter to my kid's bday party,and I knew she would find out about it cause I invited a common friend. She showed up at the playland on the day with a bunch of friends and chased me around to make me feel bad. Her daughter was wearing a party dress. I told her I had invited only schoolmates, which was true but not entirely. She pretended she was cool with it but obviously she wasn't. The reason I didn't invite her is because she excluded me from major life events last year. First she told me we were invited to her daughter's party last year and then she "forgot" to invite me. I texted her a day before " when is the party" and she replied "tomorrow". I felt awful but still took my kid to the party and gave her a present. 2 months later while I was on holidays she sent me on Facebook pictures of her wedding reception. I had no idea she was planning to get married to her boyfriend, she never mentioned it in the numerous times we chatted. She never invited me and then just sent me pictures of the party. I felt horrible and my holiday was almost ruined. Now she feels like she has the right to show up at my kid's party and try to make me feel bad. If she doesn't care, why does she bother?
