Avoidant behavior, where he demonstrates a complete reluctance to be in social situations and avoids emotional closeness, is where the big red flag exists.

Some guys who have 0 friends are constantly afraid of putting themselves in vulnerable situations where they are judged or criticized by people.

Unfortunately, prior to anything socially uncomfortable happening, he is already thinking that everyone is out to take advantage of him, and this compels him to develop a rigid self-defense mentality.

That’s where the complete reluctance to be in social situations and the avoidance of emotional closeness become so apparent.

All of this is a really big red flag, as it is a precursor for what a romantic relationship with him would be like.

A guy with avoidant behavior is a lot to deal with despite how innocuous he seems on the surface.

By choosing to get into a romantic relationship with him, it’s only a matter of time before his avoidant behavior starts negatively affecting it.

Think about past boyfriends.

How much of a role did they play in fulfilling you emotionally?

A guy with avoidant behavior won’t give you that type of emotional support.

Dating him won’t change that.

All it does is force you to keep tolerating his avoidant behavior, believing that you have what it takes to get him to come out of his protective shell and show vulnerability.

Unfortunately, his avoidance of emotional intimacy is how he protects himself from criticism, judgment, and perceived humiliation.

Basically, you would be stuck in a situation where your own emotional needs aren’t being met, while you are in a futile quest to save him from himself and free him from his avoidant behavior.

Many girls fall into this trap of thinking they can fix a guy like this, and mostly, they fail.

This is where she spends an inordinate amount of time and energy working on fixing him to no avail.

By the time she realizes that he is incapable of expunging his avoidant behavior, she is mentally and emotionally exhausted and deeply disappointed with the amount of time she has wasted.

Don’t let this be you.

A guy who has 0 friends due to avoidant behavior is a really big red flag.

That said, there are guys who have 0 friends who don’t have avoidant behavior.

Oftentimes, this is a guy who was raised in a household with overly protective parents.

Overly protective parents who were antisocial themselves and who inculcated that mentality in their child.

As a result, he is raised to believe that anyone he socializes with outside of the family is not to be trusted.

This keeps him from developing close bonds with other kids at school or in his neighborhood.

He was the child that stood aloof as the other kids played in the playground.

This leads to him growing up into adulthood lacking social skills.

It’s already hard enough for the most social people to make friends as adults, let alone someone who grows up never having cultivated any social skills.

Given this reality, someone who grows up with deficient social skills would typically end up having 0 friends.

In this case, you have someone who is a victim of his upbringing.

In an alternate universe where he grew up in a family that allowed him to socialize with other kids and make friends, he would have friends as an adult.

However, that isn’t his reality.

Does this make him a big red flag?

Maybe and maybe not.

Since you already like him, he clearly has a number of good personality traits.

Personality traits that other people in social situations can gravitate to.

In the event he is committed to improving his social skills with your guidance, casting him aside as a red flag could be a bit premature.
