Is it normal for a 15 year old to sleep in her father's bed?

I don't see the problem here.

nothing abnormal to me there :/

I'll occasionally fall asleep in my dad's bed while watching tv. I don't see the problem.

Truth to be hold more incest happens then you know or wana think! Its his daughter they probably both enjoy it and no better eay to share it with there on father. Its not just rednecks in the woods anymore with billy and sally banging. It could be anybody . But most incest is not rape. So dont think that if she going to him.. Then its both. Dont be soo narrowed minded .. Get your head out the gutter this is the real world , everybody does something , wether it be drug etc. But nobody talks about it . The news , is playing with your head not all "bad" people as you would call them look like black guys with golds and saggin pants , and fa fat guy that sits at the park with sweats on and watches your children.
But hey if not then she just sleeps with him no wrong in that!!

Sounds kinky.

Mr. Myrtos, what exactly does that mean, things went a little too far?

Not normal. No matter the situation, icky or not, boundaries are critical for kids.

I can assure you that can give him a hell of a trouble difficult to handle.
I'm a guy with 35 and I live alone with my 14yr boy and still sleep with.
I posted my concerns just a wile ago.
Things went a litle to far now and I feel caught in a situacion I don't know how to solve.
If you like your boyfriend try to do something. I already lost 2 girlfriends because of my singular situacion. (sorry 4 my bad english)

I think there's nothing wrong.

She only sees him once in a while, and he doesn't set boundaries for them. While their mother is "inattentive" and from the sound of it not a very good parental figure, he's there FOR them. Some boundaries may be good, but at least he connects with them(letting them "control" his life). So of course they feel good with him. How old is his other daughter? I actually wonder why only the 15-year old sleeps in his bed.

I think if my parents had been divorced, i would also have spent as much time as possible with my dad, including snuggling up in the evening and possibly falling asleep while talking...as long as there's no other indications that suggest something more, i doubt there's any reason to be alarmed.

In many cultures around the world families share the same bed. Sometimes multiple generations of family. Although I was never really raised that way, I was recently ill and my mother slept in my bed. And I'm over 25.

If the biological mother of the girl is inattentive, maybe the girl feels some sort of stability being with her father, and hence comfort by sleeping in his bed. If they were taking a bath together (not a shower, as I know families that shower together) or you walked in on something, then I would be creeped out.

But to me it honestly sounds like he's some sort of stability in her life. Have you offered for her to sleep with you? Maybe by giving her another adult/female view on things can break her from being so dependent on her father. But do it tactfully and gracefully. Be her friend first and then start to ask the questions or hint.

Or she could hate you, and knows thats by sleeping in his bed, you're not there taking her father away from her.

Girls are a mystery.

I don't see anything wrong with this they are family... But if it was otherwise it would be wierd

Not normal.
