It depends how the rejection went. If she was all nice and direct about it then i will respect her even more and would love to see her again (which happened to me before).
But when the girl does it in the most horrible way possible, and gets all weird about it, and not even answer the text that asked her to go out, then i would be kinda disgusted to see her again and probably would want to avoid her vision. Or if i do see her again and we happened to say hi for whatever reason, i'd be way more coldhearted and not give her a lot of attention.
Obviously I will talk to them. BUt I won't "keep talking" to them. Nothing more than a polite greeting- "hey, what'sup with you? " etc. Besides that also depends on HOW they rejected me- politely or rudely.
