so. here I am. I am 21 years old and I just found out that my biological father is my moms first husband. not my "father" I know. which isn't all bad because hes a peice of work. but not im stuck in a sad place. let me break this down. my bio dad has two daughters. one died when she was 3 a few years ago and he has another daughter. I'm not sure how old she is or her name. so I have two half sisters on his side. then I have another half sister whom I thought was my full sister my entire life. her name is anna. she has four half brothers. who I still consider my brothers because i love them soooooo much. they are my world. I am 32 weeks pregnant and im in all this mess. my fiance is adopted but he does not speak too them. he followed his birth mother to Michigan. .. she's. ....evil. psychotic. not like him. but now were both worried about our daughter. what families will we introduced her to? and who will we tell her they are? you have aunts and sort of uncles. I haven't told my siblings about what I know. or their dad. he will want to be a part of our life but....im not sure that is what is best for our daughter.
