Approaching Birth Siblings

If it's clear that your father doesn't want any contact with you, then I would hardly think that he's likely to tell your step-sister anything about you. Also, I feel this is quite a tender area, as if she's the daughter by his present marriage, she may be a little detached from you too, in that she is probably more attached to your father at this moment in time, than any of the three who were born in previous marriages. You could create a little apprehension or even jealousy between you and her if you aren't very careful. However, if you really want to get to know her... and you possibly do because she's the only other female... I would approach it step by step and carefully. Bear in mind that she's the only child from this marriage, she has been living with your father for possibly, the whole of her life so far, and is probably more attached to him, being the only one. Try to ease into her life gently, and avoid upsetting your father at all costs, but I'm afraid you will have to do this either alone, or with the help of your accepting brother. Why not discuss it with him, as he seems quite an understanding person, and will, I am sure, treat your case with all the sensitivity he can find. I hope this helps. It's difficult not knowing the personalities of people, as you have probably found out, but I've given it my best shot. Good luck and Brightest Blessings.
