Dating apps, television shows and social media has lowered the bar when it comes to commitment. In a culture where first dates have become more casual, it is more important than ever to set clear expectations when going on a first date. So what's the difference between going out for coffee and going to dinner? Moral Revolution suggests the following:
"Coffee implies a more casual interest and is low stakes for both parties involved. You show interest but also a desire to keep it light. Dinner implies a more serious intent. This communicates you're for sure interested and ready to let her know. Maybe you already know her or maybe you just know you're interested. It's more intentionally showing romantic interest."
The key is to be clear on the intention of each interaction. Have fun getting to know each other, but don't get stuck in the ambiguous "we're just hanging out" cycle. It will save you time and heartbreak.
