“Jews don’t date to “have a good time.”
They should. They should date for tachlis, but the tachlis should also include having an enjoyable time on that date. If two people cannot enjoy each other’s company (which is the very definition of having a good time), then how can they enjoy sitting across from a table from each other for fifty or so years, G0d willing?
What you said is like saying people don’t eat to have a good meal.
It’s true we need to eat to continue living, and we need to date in order to meet our basherten, but that does not and should not preclude our enjoying the meal (in fact there is a halacha that a man can divorce his wife if she burns his food, is there not?). Hashem does not want us to live our lives without fun and simcha. If we do, He wants to know after 120 years, why we didn’t enjoy the world He gave us. Dating for frum Jews IS for the purpose of finding our life’s partner, but that does not mean we should not enjoy the process.
