Advice? Rant.... Feel free to comment

So my parents made me move 5000 miles away from my SO about a year ago. We talk everyday via text because he's either at work or I'm at school. I just turned 18 and he's almost 19 but I'm not graduated yet so my parents won't let me move out. I have this crazy idea that I'll be able to visit him this summer after I graduate and take a road trip with him to see my grandmother( she's dying of stage 4 large cell lung cancer).. But because I will have a restraining order against my fathers wife we will have to get a hotel... I won't have much to spend on lodging so I figured we could get a single bed and either I would sleep on the floor or we would cuddle ( and that might lead us to other stuff;)) but I'm a Virgin and I don't think he would willingly take that unless I physically told him..also I really don't know what to do 😞.... Should I tell him about this crazy idea or keep it to my self?... I miss him so god damn much I literally get depressed when I think about us.....
