Romance after rejecting him first possible?

Just want to make sure I didn’t lock myself out of his romance. It’s the first time I picked the “I’d rather kiss a leech” option when he first propositions Tav before the party in hopes of getting the “say please” dialogue at the party. Was that correct or did I mess up? Next steps I assume are just 1. Have the party 2. Succeed in the say please dialogue tree 3. Romance scene? Anything else?
