I think you will find that this woman is a boot. You need to get her tae f***. She is using you as an ego boost. She wants to know that she is hot enough to have you if she wants and by texting her you are confirming this.
If she is sitting about kissing other guys then she's not really very interested in you is she?
I know it's hard to take, and I didn't listen when people told me the same. But I finally followed my friends advice and it was the best thing i ever did. So I will dispense this advice now:
But you have to get her off that pedestal, see her in her real light. A fuckin boot.
This is actually quite customised to me, but if you change the name and maybe one or two details it pretty much sums up what you need to hear.
Good luck with it all mate.
