My parents wont let me see my boyfriend

My boyfriend comes home in 7 days and I am so excited. My mom and dad hate him and they barely know him. They won't let me hang out with him outside of any school related activities. Thing is, there are barely any! Plus I would like to spend some alone time with him since he's been gone for 3 months. This isn't fair. They treat him and I both like shit. My parents call me a slut and a whore all the time and I just can't stand it. Ugh. I just wanna spend time with him.
