my guardian hates my boyfriend please HELP!!

Cheyenne
So let me explain a bit. My guardian is my aunt and uncle, so I live with them and my cousin. We're both seniors in high school, she's only two weeks older than me. We're both dating, but my aunt and uncle hate my boyfriend so much. We can never see eachother, if they come over on the same day, mine has to leave at least an hour before hers? She found out we had sex over 6 months ago, she was so mad I was on house arrest for 52 days basically with no technology and idek if it's because of that. ugh ladies I need some serious advice because its effecting our relationship!!
