Boyfriend's dad caught us 😖

We were home alone at my boyfriends house, we're both a month away from 18 btw, and we had decided to take a nap in his bed. Well his dad came home and found us, kicked me out, and freaked out. His parents/family are all super religious, so this was already bad enough. Two hours later i get a text from my boyfriend saying "I told them everything, like everything." He told them we'd been having sex, and literally every thing we had done. His parents now have him on lockdown, he has to walk to and from school, and hes not allowed to see me for "a long time" plus they want to sit down and have a "mature conversation" with me, but wouldnt tell me around when or anything just not in the next few days. im a volunteer EMT and I work, plus school im afraid theyre going to springe this meeting on me and i wont be able to make it, and theyll think im a worse girl then they already do.. ugh
