By seeing other girls at the same time, a variety of his personal needs are being met.

Each one provides something that the other doesn’t.

One of these girls can satisfy his need for excitement and another his need for great sex.

Basically, all of these girls have a distinct role to play in how they satisfy his needs.

He uses each girl for what they are best at providing, which makes up for what another girl lacks.

This means that neither you nor any of the other girls he is seeing fulfills everything he desires.

Since he is seeing you, there is a need you are fulfilling for him that makes you have a degree of value to him.

Notwithstanding, he continues seeing the other girls because once aggregated, they give him the fullest dating experience.

Since he is receiving so much of what he wants as an aggregate of all of these girls, it makes it that much harder for you to be special to him.

Even if you are capable of doing all of the things the other girls are capable of, it’s impossible for you to do them just as good as the one among the bunch who does it best.

In situations like this, when a girl becomes aware that a guy she is seeing is seeing other girls, she often makes the mistake in wanting to beat out those girls.

As a result, you go too far in trying to fulfill all of his needs so as to set yourself apart from all of the other girls.

Sadly, the harder you try to please him in areas that you aren’t naturally all that good at, the more he deems you as insufficient.

Even if he keeps you around for a while longer, he has already decided that you are far too deficient in all of the other areas to be worthy of a committed relationship in the foreseeable future.

Moreover, a guy who is seeing you and other girls at the same time is spread so thin he is incapable of developing a deep emotional connection with you.

He is spread too thin, making it impossible for him to center the full breadth of his thoughts and emotions on any one girl.

Since you are only seeing him and no other guys, the full breadth of your thoughts and emotions are centered on him, which makes you far more susceptible to falling for him far sooner.

Since he is the focal point of your dating life, all of your emotional energy is focused on him.

You fall for him quickly, and the next thing you know, you are acting far too needy and clingy.

When you keep seeing a guy whose attention is divided across too many women, you are the one with the highest likelihood of falling, not him.

This is a profoundly vulnerable position where you get ahead of this guy emotionally, and a neediness develops in how often you want to communicate with him and a clinginess in how often you want to see him in person.

The longer you keep seeing him, the stronger the emotional intensity, which leads to further neediness and clinginess.

This further convinces him to never take you seriously.

All of this is to say, you should stop seeing this guy immediately.
