How hard could it be

I few years back I've met a lady she was one of my employe and we start talking to each other and do stuff together i've tough that we had develop a nice relationship/ friendship. We had a lot of ups and downs together but things were getting settle quite quickly but about 2 months ago out of the blues she stop talking to me, usually she call me every single night and I do miss her phone call, and we were going for dinner at least once a week or every 2 weeks. But 2 months ago she had suffer an allergy reaction that could have cost her life, I was really worry about that and try my best to show her that I care in the way I can demonstrated it. But since then she cut all contact with by one removing me from her friend list on msn and secondly not answering my phone call. There was one time where she did answer me but her tone of voice was very cold and dry I had ask her a couple of time if she was upset at me and say many time No why would I be but her tone was not friendlier, just before hanging up a repeat the same question telling her that if I did something wrong I would really like to know it so I can't repeat myself again, no comment from her. Everyday I hope that she will call. Why people can't be honest and fix things instead of running away from it.
