She knows i love her from 3 yrs but she dosent. We are in same office. Talks to me very nicely & shares her personal talks but very limited mainly when i get into them. I kept helping along, always been on her side when she needed someone. But she never really starts a conversation. Answers my calls and msg. At first she rejected my proposal saying its too early (3months) and also she had a bf. A year later i found us in a better and comfortable position with no bf this time. Again i shared my feelings again but she rejected again. I tried to get away from her didnt any contact for 4 months bit later realised i have to talk to her and couldn't do withou her. What should i do, i want to marry her. Should i wait for her more or move on (which is seems very difficult)?
