When you’re interested in someone — whether it’s a new prospect on JDate or after a first date or after a few months — making plans is the way to let them know you’re still interested!
People can carry on conversations with lots of prospects online, but it’s only you’ve made plans that you know this one is different. And then after the first date, having plans made immediately for a second date is how you know that there’s enough mutual interest to continue getting to know each other. And once you’ve been dating for awhile, then making plans is assumed.
Whenever a plan isn’t made — regardless of the scenario — is when people begin feeling insecure about where the relationship (or the possibility of one) is going. So if you like someone, make plans to see them again, otherwise you’re just playing games.
