Girls love to ignore me, it's cold! Do I have to keep chasing?

If it was ok at first, it's getting cold now.

That only shows that she is not satisfied with your performance, as can be seen from her indifference to you.

Generally speaking, if your relationship goes well, she should rely on you more and more.

I don't suggest you continue to chase, unless you know where your problem is and decide to completely change it. There is little hope.
