I feel my relationship with my sister has completely broken down to the point where I don’t think I can have her in my life. There is far too much to put into this post but the key things are that I feel deeply hurt and let down by her since having my twin babies a year ago. She was unpleasant and unsupportive during my pregnancy and since having the twins hasn’t really bothered much. This is in comparison to the support I gave her when she was pregnant and had my nephew (who I babysat and had overnight 1-2 most months for the first couple of years) to give her a break. We’ve always had a difficult relationship but it’s gotten far worse now. She is disengaged, shows no interest and the lack of support has greatly hurt me. As it stands, I don’t think I can have her in my life and even when I have told her how I am feeling, she refuses to reflect and instead puts the blame onto me. I didn’t invite her to celebrate my twins birthday due to what’s happened and she said some horrible things about this. Her behaviour at times has been unforgivable. What would you do?
