So when I was conceived it was a one night stand kind of thing so when my mom told my real dad he insisted on them getting married but my mom didn't want to she said no I will let you be in this baby's life but I don't want to marry you cuz I'm not in love with you so 9 months past I was born well my real dad wanted to come and see me when I was about a week old my mom didn't want us to be alone with him so she called my uncle and said she need him to come over while my dad was there so my uncle and his buddy came over well his buddy Eric was holding me when he came in I was so calm and giggly toward Eric well when my dad showed up he gave me to my dad well I started to scream and cry until he gave me back to Eric so they did this two times and then he left well mom saw how much I loved Eric so they stated to talk and then a couple of months later they got married and he was the one I always have called my dad when I was 8 I found out the truth well now my mom has divorced my dad and has a new husband who I also she as a father figure now my real dad has come back in touch with me after just about 10 or 12 years I'm 20 now and he has a step daughter who he adopted and I feel abandend I mean I've been though a lot of stuff he has never given his rights up for me ever but he treats her more like a daughter than me idk I just feel like this what do I do?
