Need some advice on how to convince my mom into letting me go to my boyfriends house every morning

For a week I'd get up at 5 and take a bus that'd take me to my highschool at 630 and walk to his house from there. However my parents found out about it and I can't go anymore or theyll contact his parents and tell them what I've been doing. I've done everything I could to convince my mom otherwise and I even camr up with the idea of her telling my dad I was at a family members house when I was really at his in the morning(he works nights).

Today I told my mom about my step dad molesting me in my sleep when I was in 8th grade. She feels guilty and apologized to me for not realizing what was going on. She also told me she'd help me any way she could to make my pain go away.

So how should I tell her going to my boyfriends house every morning really helped my mood? It actually did, I felt the happiest during that week than I've felt all year. Talking to him and have sex on a regular basis really settled my hormones.

I'm 18 btw, only reason my mom is holding me back is because she has his parents emails since theyre teachers.

Tldr can't go to bfs house every morning anymore because my parents have his parents' emails, how do I convince mom to let me go, I just told her my step dad molested me in 8th grade
