Input: So basically I have an old truck I have been wanting to sell for a while because it’s diesel and I can’t deal with all the problems as a teenager right now. My parents told me they would be fine with me selling it and buying a new truck as long as I understand they still own it. So I put it up for sale and a guy wants to trade me this really nice truck in great condition because he wants a diesel, and our appraisals are almost the same and I love the look of his truck and it’s gas and I’m very good condition. 

We chatted for a while and I sent him all the stuff about my truck and he sent me all his stuff and we agreed on trading this weekend. I told my parents about it and my dad keeps blowing it off and saying he is having second thoughts and wants to research some stuff before selling the truck.

Now, this is what my dad ALWAYS does when he’s not interested in me doing something. He just keeps trying to blow it off until hopefully I forget about it. So now I am set up to trade trucks with this guy and he is keeping it from other sales for me and my dad is telling me no now after he clearly told me yes earlier.

So this is my question: am I an asshole if I cancel this deal after I told the guy I would this weekend and he cancelled other offers with people? Or is my dad being the asshole for not letting me sell it after saying I could at any time?
