Ah, well my friend, everyone is different. Being ignored, or not talked to, hurts, but it's a part of the game you have to learn to deal with.
I'll give you a real quick example, several years ago, I met a REALLY awesome dudette where I worked. Beautiful, funny, intelligent, all the right qualities I enjoy. We used to chat all the time...until I offered her to have a drink after work. She completely stopped talking to me and wouldn't say hi to me in the corridors anymore. I was taken aback. It was only a year after she had left our work place that I was told that she was Scicilian and was apparently raised in such a way that only another Sicilian would date her. She could have said something, but didn't.
So, in the end...I shrugged my shoulders and moved on. She could, of course, have told me, but it wasn't her way and to me, it was her loss, because I can easily seperate friendship from romance and we could have talked to this day, because I like to keep in touch with my friends. Some I've known online yet never seen and we've talked for over 20 years lol.
It's a sad truth, but it's a truth nonetheless. You have to learn to deal with it and move on, as painful as it can be. There's also the fact that some people, men or women, go psycho-stalker when being rejected. It makes people afraid. I can understand that too.
