I have three half-siblings. I have an older half-sister in her 20s and an older half-brother (also in his 20s, though he is younger) both from my dad's first marriage. They live in Oklahoma and I don't have a relationship with them at all, though I did get sent some pictures of my sister's two adorable babies.
I also have a younger half-brother, who is ten years old. He is from a short relationship my dad had when I was ages 7-9. I love him dearly and I'm very protective, especially since he was born in the same abusive atmosphere I was subjected to. I try to see him as much as possible, though it's difficult since his mother is in and out of rehab and prison and I never know who he's going to be with. Recently his grandmother got full custody of him so I hope that means our relationship can be more stable. There was a long period when I didn't see him at all, which made things hard, because I took care of him for so long, and that love was imprinted in my heart from the day he was born, but he didn't remember any of it since he was so little.
I have 4 brothers. The first two were twins that died at birth. The next two are older than me. The first one is six years older and the other is five years older. I also have a sister that was ten months younger than me but she passed 3 years ago.
