How can a girl show that she loves

Sometimes it’s hard for a woman to tell if a man is interested in them or just being polite. This is especially the case when he is shy or maybe is inexperienced in social situations with women. But there are some instinctual behaviors that can give you clues as to their true intentions.

Keep in mind that many men will be interested in any women that will talk to them so you might want to gauge their behavior before you make an approach. If a nice smile from across the room doesn’t peak their interest and bring them to you, maybe you should keep scanning the room for someone else.
