PROBLEMS WITH A FRIEND

Susie Williams has been my best friend ever since we were being at primary school together, and last week she told me some good news. She had decided not to marry with her boyfriend. They had been going out together for about two years, and got engaged last Christmas. I was never happy about their relationship, as I thought so that he was not the right partner for her. I always felt that if they had of got married, she would have completely lost her independence because he would have to made her give up her studies and stay at home all the day. Susie would have hated that, as I know that she is a very ambitious person, but when I was mentioned it to her she became quite angry, saying that I was jealous her, and wanted him for myself. Sometimes it isn't easy being a best friend.
