Dilemna with telling my daughter she has a half-sister
So here is the long story short. My daughter is six. Her father lived with us until she was the age of four. He left for many reasons and to work on his own battles. He is in the picture and sees her once a month typically and does make efforts. I don't want to bash him here. We all have issues. I had my suspicions when I was pregnant with my daughter he was carrying on another relationship. I had a gut feeling after I had confirmed that relationship was occuring and it ended and I took him back in that something was left unsaid. Bottom line, I found out that woman had a child within nine months of my daughter being born. I made him aware of this and early this year he had it confirmed this other woman indeed bore his daughter. My dilemna is this - this little girl is my daughter's half-sister of course. They are nine months apart exactly and the other woman gave her the same FIRST name as my daughter (yes, she actually did however I can't change this fact). Given he is in the other little girls life and sees her every two weeks like clock work and is rather sporadic with my daughter, I still have reservations. He has admitted to me he is consistent with this other child given he was out of the picture for so long however inconsistent with my child. He has expressed the fact to me and to his sister that he wants the two girls to meet. I feel it's too early and they are both too young. While I am grateful she has a sister I worry about how this will affect her TODAY. I don't want when she is 20 to find out and be angry having lost that time with her sibling however she is very sensitive and already is feeling insecure in him having been here (fact - he was here but not here if you get my picture) and now is out of the house. I want to be honest with her however I just feel she is too young at six to share this. I honestly feel she will feel betrayed. Eventually I'm excited she and her half-sister can have a relationship. I'm worried as well because he has expressed it's really his say and not mine at all and his sister has told him it's truly my say as Mom. Mind you I am the primary care-giver, only means of financial support, etc. What do I do? This isn't about me. I'm not jealous at all and am no longer hurt by this. I'm just hurting for my daughter.
