Something has changed, according to what you wrote. You used to be able to hang out together, alone; however, now Mom is following you, room-to-room. Mom is picking up on something and she may not know just what it is, yet. OR, we’re not hearing the full story, here – which is fine, share what you want to share, but as a Mom – I know that if she has made a sudden adjustment in how she behaves when your boyfriend is over, there is something going on.
You do need to sit down and talk to both of your parents and don’t get defensive. Listen to what they have to say and point out that there is a difference in how you used to be able to hang out with him, with a bit more privacy – ask what has changed, because now you are being watched, closely. However, your parents have the right to say that nothing has changed, we just feel you are getting closer and yes, we have concerns.
We have very clear rules in our house, no bedrooms – even with door open. It’s just not up for discussion. Family room, fine. Kitchen, fine. Deck…that’s fine, too. We don’t sit right with them – but we do make appearances.
Granted, right now, she’s only allowed to date for special occasions – school dance, things like that – she’s still 14. We do allow “group” dating, but they all usually wind up at our house for video games and movies. In the summer it’s for the pool.
You live in their house, they get to set the rules, like them or not, it’s their decision. Whether you believe it or not, they are there (the rules) because they love you. It’s far easier to be permissive and give free reign and assume your child will not do “dumb” things, than it is to set boundaries and follow them.
