Last weekend I met a woman and on Monday asked if she'd like to go for a drink some time this week. She replied saying yes that evening and Tuesday morning I suggested a day and Wednesday evening she agreed to Sunday. On Thursday I suggested a venue but I haven't heard back yet.
What is the etiquette here? I'm aware it doesn't seem like she's overly keen but since a day was set should I send another message or just leave it? I would rather like to go for the drink but don't want to harrass anyone or seem a bit desperate.
