So, my half sister and i havent spoken for over a year almost 2 years at this point due to some family drama that was started by her on social media about my dad who has always been a good father to her. When she called dad the other day trying to mend fences, he let it slip that I'm getting married in October. Well, after they got off the phone, she texted me asking if she was invited and if her daughters got a plus one. I explained to her that we hadn't made the guest list but we did know that anybody under 18 or not in a committed relationship would not be getting a plus one. Well she sent me a very nasty message and then while I was at work, she called my dad to ask him and he told her shed have to talk to me about it. I understand she is my half sister and they are my neices but I don't want a strange teenager I haven't met at my wedding. It just kills me that she only came back into my life because she wants to be part of my wedding planning and wants my attention now.
