I am 19 years old, I have been with my boyfriend for almost 2 years now. I am trying to talk openly about sleeping over at his house on occasion. He is allowed to stay with me at college and my parents know we have group sleep overs at a friend's house but whenever I bring up staying at his house it is a closed discussion.

I have lied before about sleeping there and been caught and we talked about it but all they say is they don't agree and do not want it happening. Then they say they cannot trust me because of things I did when i was 14 and 15. I have never had a good relationship with my parents and every time I tried to talk to them they shut down so I used to lie because I felt I couldn't talk to them about anything. I don't lie any more as I did when I was younger and rebellious, I will be 20 in a few months and I want to respect my parents wishes while I still have to live under their roof but I want to communicate with them and show them I want their trust and they have no reason to not trust me anymore and by talking to them I am showing them they can trust me.

I tried to express that I am not doing this to defy them it is just easier sometimes and it does not mean we are having sex. My parents know I have had sex and they know I am safe about it. But that isn't the reason for the sleepover. They are not open about talking about  me growing up and the closer they try to pull me the more I want to pull away. How can i express my feelings to them?
