Hiya, i work in a childrens home with VERY troublesome 11-18 year old teens. This is a difficult one.... Yes she is only 16 but by the same token she is 16 and should no better than this. Sometimes tough love is what is needed. The key here i would say is not to 'just chuck her out and leave it' but to move forward and use this to your advantage. Most kids want to be at home in the long run and once shes had a spell at living away from home for a while she'll prob want to come home, if this happens you are back in control. At that point you need to tell her you love her, miss her and would love to have her home but agree on some ground rules........ No shouting, no arguing just clear cut boundaries for her to adhere to. A suggestion for this is not to create your own rules but to discuss the problem areas with her and both agree on the solutions that you BOTH need to adhere to, that way she will OWN the decisions and be more likely to adhere to them.
Faling all this and her not wanting to come home, you will prob find that you will develop a better relationship not living together.
As for her education etc, yes your prob right shes more than likely that so tied up and inflenced by her chap that shes messed it all up, but, all the nagging in the world isnt going to make it better, its got to be her decision. Remember this... If you have bought her up with good morals and values etc (which ive doubt you have)no matter what she does or experiments with in her teens, those values will be instilled in her and will come oozing out and put her back on the straight and narrow.
Also, if her chap isnt working or anything they will prob get sick to death of each other, also money will be tight which of course creates even more problems as we all know.....
sit back and wait, but STAY CALM!xxxxxx
