curfew

So I'm 17 and it's summer.  I have had the same boyfriend for 2 years already he's graduating and I'm going to be a senior. Lately I've notice my parents being more strict with me and they don't let me see him all the time. They want me and him to have "our space" sometimes. Also they want be home at 9-10pm or later like 11 depending of the occasion. I've talked to my mom  about it but didn't really say anything. Any advice on what I should do?
