do you think my plan will work?

i’m 16, me and my boyfriend been together for over a year but we hardly ever see each other after what happened in march. we had sex and my mum found out through text messages. those few months were the worst, i was beat up all the time, abused physically, emotionally and mentally. my mum bullied me for what i’d done. she tried to do a surgery on me to stitch up my hole and make me a virgin again when i told school the police got involved from this day my mum still goes to court. i love her but i don’t love how she treated me. stuff has calmed down and i miss him. we want to go on a date! so i told my mum i’m going cinema with an old school friend and she said she will come for a bit to take pictures as proof that i’m with her but now she told me she cant ( i have my mum on snapchat she said i have to put pictures up and i have to show her pics of us two together but i can’t, well, i asked her for pics of herself at cinema like 10 mins ago bc she told me she has them but she still hasn’t sent, i’m waiting though guess i’ll use that) she can’t come bc her mum told her to stay at home. i’m so scared. most times i’ve planned to see him something happened where my mum would find out something a few days, the next day, the same day or even a month later. what if that’s god trying to tell me something? anyways, i love him and the main main reason my mum hates him is because he is black. i’m scared if she finds out, will she?
