Already tried that. She refused point blank.
If you sincerely apologized and offered to be friends with her, then you can at least say you tried to make something out of a bad situation. Sometimes people just need to get away for awhile before they want to talk again (based on my experiences). Or sometimes they just want to move on from the situation as a whole, it really depends on the girl. I figure for most people that it's really tough to move on from someone you've liked for a long time, even after about a month or two without talking. But it really depends on the personality of the person, maybe it's not bad for them. Can't say.
In any case man, if you apologized from the bottom of your heart and made a good effort to try and be friends again, that's all you can really ask for. It's not easy to deal with forsure, but I'd hope I'd be able to sleep at night knowing I tried everything I could in my power to try and make a solid friendship after a big debacle. It's not easy, but you tried man. Sometimes they need time, and sometimes it might be best to move on. Experiences can make us better people, so hang in there and look at the big picture so you learn form it.
Glad to know you are doing better, keep your head up! Things will get better!
