My daughter and her boyfriend are driving me crazy...

[redshirt32]

A few weeks ago I caught my 14-year-old daughter kissing her "boyfriend"...
I warned her that it is not okay and that it better not happen again...
A week later, the boyfriend's mother catches them kissing but doesn't tell me...
A week later, my wife catches them kissing with heavy petting and does tell me...
Sheesh, I think, what am I going to do? 14 is too young!
So I talk to the both of them and say,
"Do you two wanna keep seeing each other?"
They reply, "Yes."
"Then cut the kissing and stuff out or else you're done."
My daughter later promised me she would do as I asked.
Last night my wife caught them kissing with heavy petting again.
And, of course, she tells me this as I'm going to bed.
So I call Katie out of her bed and bring her into our bedroom.
I confront her and she confirms that she did break the promise.
(Who knows how many times.)
I told her she screwed me and screwed herself.
That I was very hurt that I could no longer trust her.
I also told her she was through seeing the boy;
and the boy was not welcome in our house;
and there would be no further boy-girl social occasions
of any kind: parties, holidays, outings, or the like.
Lastly, that if it gets back to me that she is seeing the boy,
or any boy, behind my back and I find out there is kissing and
heavy petting going on, then I will immediately transfer her from
her school that very day.

Well, was I too hard? I feel like she has been lying to me all along.
What would you have done?
