When men lose interest, it is often because they feel too much pressure. So to add even more pressure is not a good idea. Even if you want to know where you stand at that moment, give him some space to make a choice. This way you will increase the chance that he will eventually choose you.

Why did he back off all of a sudden?

1. He is scared of his own feelings. Perhaps the biggest reason why men pull away early in a relationship is because they are scared of how they feel. Whether or not they were actively searching for love when you met them, the feeling of suddenly falling for someone is full of uncertainty.
