My dad and my biological mother divorced when I was 2.

She initially had custody of my sister and I.

My dad saw us every other weekend.

There was quite a long drawn out custody battle in court.

She was declared an unfit mother.

My dad eventually got custody.

She pulled the middle finger and never saw us again.

My dad remarried my mother.

My biological mother eventually agreed to sign adoption papers to my mother when I was about 6 (we had not seen her during this time frame because she had no intention of seeing us).

Yeah and that's about it really.
