Do you love her? Does she love you? When we get into whole and half that can sometimes only cause problems. I think like this, if you have known each other as sisters your entire life, don't look into things that what bring a wedge into your relationship. Pray about it. I wish you all the best

When I was two, my mom and dad divorced. Mom remarried and had 4 more kids. I have 3 sisters and one brother. Even though we are not full blooded siblings, we are full hearted siblings. It's not what's in the blood or the DNA, it's what's in the heart.
Sisters are sisters irrelevant of blood group.
All are brothers and sisters of the
earth and beyoud.
