how do I help?

She doesn't have to accept the half-sister but she might be missing out on getting to know a very nice person. It isn't the half-sister's fault that their father cheated, so why not forget that, now that he is gone, and at least give a relationship between them a chance.

She doesn't really have to accept her as a sister, but she should still make the effort to get to know her. Like the previous post stated, it's not the half sister's fault. But the half sister might have feelings of acceptence towards your friend. If one sees the other as a friend, and that one sees the first one as a sister, then every one wins I think. But of course that is only if they want to act right away. More times than not, it's always best to wait for the clouds to pass by before becomming active. The clouds of uncertainty will move on their own as time passes, and at that time, she can decide if she wants to accept her as any thing or to leave her be for all time. The most important thing though, is what type of person is your friend? Every situation, and every person is different, so you have to ask questions, and find out which is the best plan. Most likely people over the internet who have never met her will not be able to tell you the plan of action, or which steps to take. We can, however, guide you in the direction we think is correct. The main question is: Is she afraid of the situation changing in her family, or does she hate the situation? Of course, you can't ask her that right out, she wont be able to tell the difference. Either being scared, or being full of hate will alter one's perception. There are all kinds of small questions that come to mind as well. Is she an only child, or a big family. Is she shy, out spoken, or some where in the middle. Again, not a situation we can tell you what to do, no miracle cure, or any thing. Only thing we are able to do is guide you until you find the answer. Good luck, and I hope the best for you and your friend (and her half sister).

Hi boxervseible, Your friend has to make that decision for herself. For myself, I would try to get to know my half- sister. This happens to many people, and some never have that choice. She alone must decide though. Blessings.
