Prom Ideas??

So here is the deal..
this amazingly sweet guy asked me to prom a week ago. We used to date and he took me to our old "spot" by the river and carved our names and prom? in a tree. i said i wanted to go just as friends and he got upset and said its all or nothing pretty much. So, over the last week i have thought alot about it and if he makes me happy, why not move on? why not just let it flow? its a long story to explain the whole thing but the point is, i want to ask him to prom and i want to do something super sweet but idk what to do???
any ideas??

I think if you still like him and want things to work out just go as friends he needs to give you time to figure out what you want to do? Do you want to try to work things out? He shouldn't be mad or get upset he needs to respect you before you decide to go to prom talk to him sit down and talk to him tell him how you feel as for doing something sweet go out to a nice restaurant light some candles and just let it flow if its meant to be its mean to be just don't rush into things then you would lose the friendship that you have w him I wish you the best!!! I hope I helped
