I don't really know what to do with regard to my sister. She is 38, divorced with 2 kids. It is my 40th on Saturday and we're having a big party for friends and family. Today I received a text - not even a call - saying 'hi babe need alternative dates for birthday as got house stuff this weekend.' In other words, she's not coming. She then texted to say the boys are acting up and she doesn't want to take them on a long car journey (she lives in Devon, we're Bucks.) She was happy enough to dump them on me last week - even though one of them was sick, which she didn't warn me about - so she could spend time with her boyfriend! The party has been booked since Jan. She has form as she didn't come to my wedding, 30th birthday party or either of the births of my kids. Lame excuse every time. I got her her first job, let her live in my house for free, organised 2 hen dos for her, was maid of honour at her wedding (in Italy), arranged a big 30th bash, and have been there endlessly for her and the boys, dropping everything to go to Devon after tearful phone calls. She has always got some crisis going on that is is far more important than anything happening in my life, so she never asks after me, my husband or the kids, or comes to visit - she just sends the boys when she needs a break. Last time she asked me to drive to Devon to collect them! She doesn't work - I do, and have kids, horse etc. She constantly complains that her family doesn't support her enough. Last year I booked a break for both our families in Somerset - she didn't turn up, or apologise. I paid of course. Yet she makes out like we're close. We're not. I've told her today this was the final straw for me and our relationship is over as far as I am concerned. It's tricky though as I don't want to make things awkward for our kids, who are close, or my brother and mum and dad. But I really do feel like I am through with her. The relationship has caused me misery and stress for years. It's been entirely one sided - I give, she takes. I don't want to carry on like this. What would you do if you were me? Sorry about this rant but I am sad and angry! I would welcome any ideas as I just don't know what to do for the best.
