I had a lot of freedom, and she trusted me. At 16 I was allowed our with my boyfriend until 2, yes. I was even allowed to sleep over a this house...shock, horrorshock - yet you won't allow your dd to be out without having a tracker on her? So - you won't trust her? Personally, I had to be back indoors by 5pm at the age of 14, unless I was going to a prearranged 'disco' or the like. If I wasn't, dad would be out, looking for me. There are rapist and murderers out there, you know! It's called 'being a parent'?
Yes, you are a controller. I'm not being nasty in the slightest - I am quoting YOUR words back at you. YOU SAID you will be putting a tracker on your dd at 18 (of course NOT your 4yo! I'm talking about when you should be letting go of your ADULT child) and I have told you what might happen to her - you love her so much, she can't do stuff, or go places where you might worry. So = you won't trust her. She won't have the choice to turn it off, because YOU SAID it's a bad person (me) who doesn't allow herself to be tracked.
You want to control what your 18yo dd will do. Even if it's just to lie awake and worry until she gets home. What happens is you'll be saying stuff like 'I was so worried, dd, I lay awake until 3am waiting until I could see you'd got home....' [sad voice] and it's a short (guilt trip) step from that to dd changing what she does. Either NOT going out because mummy doesn't like it, or leaving her phone at home. SSHe knows she can't turn it off, because she'd be a Bad Daughter. But she'd be ripe for a controlling man to pick up, because she thinks it's normal to be tracked, and watched, and she has no choice.
And your ds will watch this and think that it is normal for him to put a tracker on his gf (when he's old enough, obviously!!!) and watch what she's up to. And as the son of a controller, he will find it totally normal to control what she does and where she goes.
These are all hypothetical GF and BF. Just to make it clear to you, it's for when your dc are old enough to be adults.
BUT - if you stop watching the sensationalist TV and rapes and murders, and read a few of the Relationship threads, where women are controlled and abused in exactly this way, you would have a clue. Abusers like this are much more likely to happen to your dd - esp as the dd of a controller.
Honestly, your posts make my blood run cold. 'I'm the least controlling person ever'?? Said every controller, ever.
