So I've been gaming this girl for 2 weeks, already made out and she is clearly attracted to me, we've a lot of hobbies in common and she keeps throwing IOI's left and right.

Today we were having some fun playing LoL and then I decided to take a break, when I came back I realized she was playing again and told her we should play the next game, she says she can't and I find out she is playing with some other dude that she also played with yesterday. (This shit is hilarious, I know, and I promise I ain't 15.)

Therefore I act aloof and tell her no problem, I'll just play alone, she then says we can do the next one after that, so I reply that I am not interested anymore, she then keeps sending messages as ":(" and shit like that, to which I don't reply.

Is this the best approach? If it is, how long should I keep it up? I was planning on doing a week since tbh I don't really care much.

Edit: Yet another message, "You're gonna ignore me? Its ok, I don't care."

Follow up in case anyone comes across this post: In the end, I was basically soft nexting her and didn't really follow up her last message, and she wrote to me once again the next day, sending me a sad emoji, therefore, take everything you read here with a grain of salt, as right now she is really into me and we've been doing our thing really smoothly. Anyways, this will probably only work if she is already really invested into you, so make sure to not try to appear bitchy when you're just meeting each other.
