She's a pain . I began the relationship with dh , when she was 11 . She's now 21 married , and a mother to 2 herself .
To begin with she was pleasant child , apart from usual naughtiness you'd expect from teenager. Nothing out the ordinary , just usual , little bit of cheekiness , little it of rebellion ( staying out past time to come in ect ) . Like i said usual stuff. Until I dh and I decided on adding to our family.
When I became pregnant , she became a nightmare . And has stayed that way . She even banned me and her half siblings from her wedding.
To cut a long story short . Dh will always love his dd , as he should , even if he doesn't like her behaviour at times. He does not want to fall out with her , or risk missing out on his grandchildren .
The grandchildren have been kept away from me and my dc also . Shame , but I accept that and am not going to cause a fuss over something I can't change.
However adult step daughter has developed a very odd habit of phoning Dh at inappropriate times , first thing in morning , last thing at night , during films were watching , and generally at times when she knows via Facebook that we are doing something .
This morning it was 5 past 8 , to tell dh she had been to see a psychic . Apparently the psychic told her that Dh will phone her to appologise for something in the near future ... Why did she feel the need to share that when we are in the middle of getting everyone up and out to school and work ? Could it not have waited until after work tonight when he's got time to speak to her .
I am truly the "wicked stepmother " today .... After he tried a few times to get off the phone nicely without upsetting her , I started making "sex noises " in the background .
So I think the psychic might have been right after all ...Dh will need to phone her later to appologise for the " sex noises " 
.
Hopefully it will make her chose the timing of her phone calls a bit more carefully ! .
