Because many times there will be accidents, and one day your friend will accidentally bring another friend. Maybe he is a handsome boy. Maybe it's a beautiful woman, or maybe something happened on the right date one day, and your friend took you to another circle of friends.
There is love at first sight, but not too much. It takes some chances and luck. So in any case, to develop a relationship, I would suggest that you can associate with others and get to know more people with the purpose of developing feelings.
But I would suggest starting with ordinary friends, then finding friends who can talk well, and so on, to expand in this way. Therefore, in our conversation, we can clearly or often see the male friends around her.
Whenever someone gives her an olive branch, she will respond in a manly way and refuse others. But when the other person has a girlfriend or is married, she really opens her eyes to see others and observe others.
Of course, if we can accept that we are single, then there is no problem. I only bring this up for you to have a good look. Is it really because the people you associate with and know are not enough to impress you, or is it because your heart actually refuses feelings? This is where you need to see more.
