Her best friend told she already rejected a proposal and she is not that much interested in relationships
Girls, I have crush on my junior, she talks to me, gives me instant reply text message, never text first, she is kind of introvert, what should I do?
What Girls Said
If she is not interested in being in a relationship, then you would be better off to let her go, unless you don't mind being rejected.
The problem will be that if she does reject you, she will also likely to distance herself from you and then you will not only have lost her interest but more likely also a possible friend.
It is up to you to carefully weigh the pros and cons of attempting to get more than simply a platonic friendship. More often than not, such situations develop rather negatively to the disadvantage of the one confessing the liking for the crush.
If I liked a guy but he ain't interested in a relationship at the moment, I'd rather hear it from him than his friends. Because then I'd know I shot my shot and there's no room for uncertainty or what "could have" been. It's not like someone can turn down a confession on behalf of anyone else. Life is short, it's not everyday you meet someone you want to date. I'd say go for it. Just be respectful.
She is not ready, but you don't sound ready either.
