Is this a normal father daughter relationship?

Far from normal , shes far too old to see "daddy" in this way

I think it's normal for a daughter to want to see his father naked (the same for a son wanting to see her mother naked). But that kind of behavior usually happen when they are younger than 5-6 years old when they discover that women and men are different from each others. This behavior shouldn't be encouraged by the adult.

That being said i think 10 years old is very late for that kind of behavior and i think the children should be examined by a professional in mental health right now.

But the first thing to do is call the police and put the father jail, incest and abusing a 10 years old girl is not only illegal it's disgusting.

Seriously you've seen a crime and you should get to the police right now, don't bury you head in the sand and give this little girl a chance to live a normal life. And if you have been able to look at this for 8 month before doing anything, get some help yourself.

Thanks a lot for your answer, Toni2,

I am a new user and first time here. I feel hopeless for a long time on this on going situation.
I told my boyfriend regarding my concerns. He is 56 years old guy has very strong sexual desire. The daughter is adopted from the Romania. He told me he is not going to stop to do that. There is nothing sexual; it is just show her his love, which she needs it. I agree with you that she might get herself in problems in the future relationship with other boys. But, how can I properly to approach a conversation with the daughter and without hurt her feeling though?

Thank You Diana. I am happy I could help you. You need to move away from that 56 year old man. He is no good to your future or anyone else

The more you make things slide the more that man will continue to do the things.
