GOT CAUGHT

hi everyone! i'm hoping you can help me😁 last night my boyfriend was over at my house. my parents weren't home yet but my brother was in the other room. when my dad came back home he saw that i was on my boyfriend's lap and it looked terrible😩 but he had took my phone and i was trying to get it back so i wanted to get it back and i wanted get have control over him to get it back. 
i doubt that my dad will believe that story though due to his trust issues with me before. i don't want him to be thinking bad of my boyfriend bc he honestly really is a sweet guy and he is really respectful of me. i really hope that my dad will still let me hang out with him bc i really love him :/ please help me get my dad's trust back😞
