Hope you start feeling better Albel, Hopefully things work out with you and Dawn at some point. It's obvious how much you care for her. Also, I believe patience has a different definition with some women. It seems more like your expected to do the right thing at the right time,nearly to perfection.
I suppose I'm not one to coach you on relationships since I have been through very few myself but sometimes waiting for them to come around works. Of course us guys aren't normally that patient especially when we truly care about them and just wish they would understand how we feel.
It's unfortunate Dawn won't talk to you. If you could talk to her, and she would actually listen, I think it would be the fastest way to patching things up between the two of you.
