After a paternity test when my LO was 18 months old she has starting seeing her biological father (once a week for the last 7 months). He took her out for the first time last week. I have no contact with him and all visitation is done through my mother. I have now seen photos on facebook of my daughter playing with people I don't know and have been told she saw her father's family too (I really don't like them). It makes me very uncomfortable and I don't want my LO leaving town with her father again. I might feel differently if she could fully describe her day. AIBU?
