How do i get a date with a sim girl when i cant keep finding the same one over and over?

The dating option came up at the Volcano Feast, so you would have dated a Sim there after calling them on the shell phone.

Other than that, in the world of Sims, you need to gain a close enough relationship for the flirt option to work, which will eventually be followed by an ask... on date option.

Also, if you called a Sim at the Volcano Feast, invited them, and the clicked Yes to "do you want to date this Sim", they will follow you around whether you like it or not, which makes keeping track of them much easier.

If there is no Sim following you around, then you haven't yet made that call on the shell phone, so click on your Sim, call someone, and invite them to the Feast. Their coming constitutes the date, so all you then have to do is pay them attention and follow the prompts on screen.

Separately, if you want a Sim to stay put long enough to build a relationship, then you should simply stack up talk/chat, talk/chat, talk/chat, talk/play actions whilst they are still obeying the first click that gets you the conversation. Unless they have been programmed to go off and work or pass out with exhaustion, they can't get away until your Sim has done with them that way.

You get date calling sim from hot springs. Watch time, they hate being woke up.
If you talk to sim at least once, then you can call them to "just talk" and build up friendship. They will call you too. When friendship is built up, call them from hot springs for date.
I saw cute blond in market, never could catch her to talk to.
Sometimes if you invite sim over with friend you'll meet new sims.
I wind up dating cute maids.
