He may be interested in you if he smiles at you consistently.
When he also gives you a lot of eye contact as he smiles, there is a very good chance that he is attracted to you.
Now, you should be really careful here. There are some guys who just smile for the sake of it. It may just be second nature to them to smile without much thought.
You don’t want to find yourself getting caught falling for a guy who just smiles for the sake of it.
You don’t want to misread that as a cue for romance or interest.
You have to be able to be as perceptive as you can here.
The best way to tell that he is smiling at you out of romantic interest is if he continuously does so, maintains lingering eye contact in the process and leans or starts moving his body towards your direction.
These are very strong body language signs of romantic interest.
If you don’t know this guy at all, this is an even more powerful reaction to you.
There are a few other things you have to take into perspective.
Is he a flirty guy?
There are guys who are natural flirts.
Being that they are natural flirts, they develop a certain kind of demeanor.
They may always be in flirt mode when they are around girls.
Part of that mode may involve smiling.
Hence, they get very good at smiling at girls and making them feel like they are the only girl in the room.
He may not necessarily have any real romantic interest in any particular girl that he smiles at.
It’s just that he is a natural flirt and enjoys the game.
To take it any further than flirting may be too much for him.
You may be dealing with a guy like this.
You may mistake the fact that he is smiling at you as a sign of romantic interest when in fact he only does that as part of playing the game of flirting.
Try to observe how he acts around other girls.
Does he smile at them as well?
Do you notice that he tends to look at each and every girl in the room almost as though he is prospecting?
Do you see him selecting particular girls to smile at while moving his body towards their direction?
These are all signs of a strong flirt.
If this is the case, you are not necessarily someone that he would want to pursue anything further with.
You may simply be like every other girl he flirts with.
You should also observe what he does with his hands when he smiles at you.
If you notice that he preens, he may actually be interested in you.
Preening is when you see him adjusting his clothing, jewelry or rubbing his hands through his hair or beard.
He does this to make himself appear more attractive to you.
He doesn’t want anything to be out of place.
He is in essence sprucing himself up in your presence.
These are very strong signs of interest.
When you observe this, he may be unconsciously sending you the signal of interest without even realizing it.
A guy smiling at you is a good first step.
It doesn’t always mean that he is interested.
However, if you make important observations, you will find it a lot easier to tell if there is any romantic interest.
