Use online dating gta 4
The first type of relationship is any that Niko has with various females he encounters.
These relationships take on a more light-hearted and pseudo-romantic tone and are completely optional for the most part.
There are two females in the game you must date—Mallorie's 'friend' Michelle and the O'Reary boys' sister Kate—but other than that, dating is completely optional.
So now that you know how you can potentially score a date with one of Liberty City's beautiful single females, what should you do when you're on a date?
If it went well, then you can expect another date, but even girls subjected to really bad dates can be salvaged. Wait a few in-game days at the very least before you call a girl for another date, and be sure to keep an eye on your relationship meters to see how much a girl does or doesn't like you.
This is the best gauge to see how well you're doing with any girl.
This is the best way to get plenty of insight into what a particular girl thinks about certain activities. If she loves it, you can go back another time, but not the next time. Perhaps the most difficult part of any date in GTAIV is the end, when you're bringing a girl back to her place (likely swerving all over the road and killing innocent bystanders since, y'know, you're drunk).
The game will give you an option to say goodnight or to try and go into the girl's place with her.
In fact, without building up relationships with myriad characters in the game, you're going to miss out on a lot of what the game intends for you to see.
