So basically I found a girl about my age on a online video game and she actually was nice we played a lot of games together and in the 5th day of knowing her she gave me her number and we would regularly text every day and it was going nice we made other friends and we made a good team but I had told some of my other buddy’s that I liked her and they gave me tips and all so I decided to ask her a couple of days before my birthday and when I asked her she said let me think about it and she told one of my friends that she didn’t know what to say and she hasn’t responded to me or him it’s been 2 days now what do I do
