Ok guys I met this HB ON7/8 three weeks ago in college. (Location London)

WEEK ONE
I made the first move but did not show too much interest. But her IOI was very obvious and she was very much into me . the same day I introduced my self to this girl she came with me to pick up my brother from nursery and we exchanged numbers and all. I did not want her to think I was too interested so I was very laid back about everything and she made all the effort in our contact basically.

WEEK TWO
She still made the effort but I think she was beginning to get annoyed about how I am treating her. And perhaps felt I wasn’t interested in her the same way because she claimed that i am horrible to her and I never respond to her text quickly enough and that she is the only one that makes the effort for us to hangout.

WEEK THREE
One of these guys I play football with in college began to talk to her because she was there watching us (me) play. And one day of the week we went to the college gym. Because she wanted to work out and I was basically telling her how and what to do and i move on to other ppl who required my help whilst this same guy is literally following her everywhere . Perhaps I should have showed her interest at that time because she was actuly coming to me many times when i acted like the guy following her dint mean anything to me and helped other girls in the gym how to work out

NOW
In the past three days the table is turned and now i am making the effort and she is responding to my texts very late . I may have also made the mistake of giving her my fone whilst i was playing football in week two. I am assuming she had checked my text and found 102/108 of dem wer between me and her. Maybe she saw that and felt that she is too important for me to loose and changed the way she acts

WHERE IS IT THAT I WENT WRONG . is it evident to you guys that she is no longer interested? should i move on or should i ask her warg1?

Sounds like you didn't escalate quick enough and she got bored. If she says anything like "you're ignoring me...I'm always making an effort for us to hang out" that is a massive IOI. She's working to build the relationship - she's invested in you. You have that attraction. You should have kino escalated during a day 2 within the first week or two, and you prolly would have got an f-close by now.

Rather than trying to mend this relationship, freeze her out for a while and game other girls. If you start texting her more and trying to apologise or fix the situation she will peg you as a fucking pussy and you will never have a chance.
