The girl may not have brought up the fact that she had a boyfriend because she may have truly believed that it was just conversation that she was having with this guy.
Some girls are not always thinking about a guy’s ulterior motive in talking to them.
A girl may simply be making conversation because that is what she does.
She is a social person and has no problem keeping a conversation going.
She is not necessarily approaching her discussion with the guy with the thinking that he is hitting on her and she should probably tell him that she has a boyfriend.
Unless the guy has been obvious about this from the start of the conversation, she is most likely going to make the assumption that this is merely conversation.
She would feel awkward if she were to assume that this guy was actually trying to hit on her when he has shown no real signs that he is in conversation.
If she were to simply say that she had a boyfriend completely out of context, it would seem forced, somewhat rude and may not really make much sense to her.
If she is talking about a particular topic with this guy and she just suddenly started mentioning a boyfriend when it didn’t really fit into the conversation, it would seem out of place.
To avoid being constantly in this position, you will need to start making your intentions obvious from the start of the conversation or just come right out and ask her for her number or a date.
You are better off when you have more genuine intention in your approach than when you are simply conversing in the hopes that she will warm up to you.
A girl is not necessarily going to tell you that she has a boyfriend in conversation because she may not think it is necessary.
As I mentioned earlier, unless you were clear in your approach and in your intentions to romance her, she would assume that you are simply making conversation.
It is up to you to change this kind of experience.
You will have to be the one to start off with the obvious flirting or even asking her directly whether she is in a relationship with someone.
In other words, you really need to be clear with your intentions.
If you are having a conversation with her because you are attracted to her and want to take her out, tell her that relatively soon while you are interacting with her.
You can’t go around having conversations with girls assuming that they are just going to come right out and tell you that they have a boyfriend.
This is often too presumptive and most girls would not necessarily do this unless it felt natural bringing up the fact that she has a boyfriend.
You are better off being clear about your intentions from the start of the conversation or very soon into the conversation than on relying on the possibility that the girl will tell you that she has a boyfriend in conversation.
You would save yourself frustration by doing so and you would make it easier on the girl to know where you are coming from.
If she only thinks that all you are doing is making conversation, she may not even think about bringing up the fact that she has a boyfriend because she doesn’t know that you actually have romantic motives.
