Hi! kat
To answer your question about your sister who has no sisterly love Perhaps if I told you about my sister it would be of help to you She showed up out of the blue at the very moment that I was getting married,and she made such a stink about my getting married to my wife. She sure did turn lots of heads,and I could see in the guests eyes. What are you going to do about her? I took her aside and told her that Mary was to be my wife, So Please shut up and let me live my own life, and that if she couldn't do that, I would Throw her out if she continued to mess up the wedding. She left. And that was 53,years ago. Never saw hide or hair of her after that. Yes you can live very well without her in your life, As you can Plainlly see that she's cure not a blessing in your life. As for your past, all That I got to say is, "Thank God that he doesn't keep score or heaven will be empty". You need to keep on loving her, But that doesn't mean that she has the right to mess up your life or your family. Do like I did. Tell her to get lost. You don't need her in your life. But do leave the door open as sometimes things change between our ears.
