The majority of girls will tell you they have a guy if you talk to them. Some not because they truly have a guy, they are just using that as an excuse for their reasons. However, if you like the girl and want to find out, any of these three ways will reveal it.
(1). Ask her out on a date. After telling a girl how you feel about her on a date and she tells you she is going to give you feedback, know that she does not have a guy. Because a girl who has a guy will try to tell you right from time.
(2). Ask her questions like, “ name few things you and your partner appear to have a common.” if she has a guy, she won’t hesitate to talk about him.
(3). Through normal discussion: Just from one topic to another, you can talk about relationships and ask a question that will touch it. If she has a guy, she will tell you.
However, for some girls, it’s difficult to double date. So, once you know she has a guy and she is serious with her relationship, you just have to let her be and maintain a friendship with her.
