In my methodology, when it comes to online dating, the first meetup is equivalent to the "approach." It can then transition into "Date 1" if both parties are interested in continuing to explore a romantic connection. This transition can happen on the same day or later, depending on how quickly both individuals choose to move forward. In some cases, it may lead to a same-day lay, or it might happen on a later date.
Meeting someone through OLD is basically like going on a blind date. You’ve never met in person, you don’t truly know what the other person looks like, and you're unfamiliar with each other’s body language or energy. That puts you at a disadvantage compared to cold or warm approaches where you’ve already seen and felt that in-person dynamic.
Needless to say, and as most people suggest, your first meetup should be low investment: grabbing coffee at Starbucks, taking a walk in the park, hanging out in a parking lot, smoking weed, etc. If the vibe is right and things are progressing well, then you can transition to a second venue or activity, like getting drinks, bowling, checking out a ribfest, axe throwing, or whatever else gives you more time together in a fun setting, which would be considered "Date 1". Again, this can also happen in another meet up or day.
That said, I think your issue might be that you weren’t fully tuned in to her signals or adapting to her pace and mood. You need to learn how to read the signs: when she’s closed off or defensive, you back off. When she starts giving more open, inviting signals, that’s when you move things forward. You escalate until you get a red light, then you pause, observe, and wait to see if she invites you back in through her behavior or subtle cues. You grabbing her waist at the end of Date 2 may have simply been too late or was out of sync.
