If he doesn’t talk about his family, or changes the subject anytime you bring it up, it’s a sign that he has no intention of making the introduction.
As I mentioned earlier, when a man is serious about a woman, he brings her into his world.
When a guy is serious about a woman, he shares himself with her.
He lets her into his world and shows some level of vulnerability. Men aren’t used to opening up and showing their emotions and they are much more selective when it comes to letting people in.
It’s his way of letting you know that you aren’t a deciding factor in where he goes and what he does. He tells you he doesn’t want a relationship This seems like an obvious one, but unfortunately, it’s not!
