Maybe he doesn't want to 'lose' you... Maybe he's scared for you... He knows you had a sheltered life, and frightened by what may happen with bf's and such when he's not there to watch over you... I'm not saying his behaviour is right or even remotely acceptable, but isn't that a possibility, even a slight 1? Btw, I'm nearly 28 and have never had a bf stay over, house rules and I respect it, I don't find it unreasonable at all. I just went to spend the night at his place (ex bf now). I can't leave home, not yet anyway, my mother's elderly and confused, so I have to wait until my eldest sister extends their house and has a place ready for her. We can't change our parents, but we can cut the chord, leave as soon as you're able to. Simple. He can't make you stay. What's he gonna do? Tie you up? Call the cops, and tell them what? 'my adult daughter wants to leave'? You have a choice, take advantage of it.
