It’s best to keep it short and unambiguous when telling a guy that you are not interested in him.

Use a succinct phrase such as, “Thank you, but I’m not interested.”

It is that simple.

Though it sounds a little harsh, it isn’t.

If you are worried about hurting his feelings, don’t be.

You aren’t responsible for how a guy feels about rejection.

This is something that a guy has to deal with on a personal level.

The sole responsibility you bear is to be honest and true.

By giving him an ambiguous answer, you are exacerbating the situation and making him believe that there is hope when there isn’t.

In giving him your phone number on account of being too afraid to be honest with him about not being interested, you have given him hope.

When he uses that phone number and you choose to ignore his phone call, or you have a half-hearted conversation with him, how do you think you make him feel then?

Saddened.

You are better off being straightforward right from the beginning.

A reluctance to do this, has him believing he has a chance.

This prolongs this situation indefinitely.

As time progresses, he gets more emotionally invested in you, thinking you might like him, when in reality, you don’t.

If you want to be kinder in how you deliver the message that you aren’t interested in him, say this:

“I rather we get to know each other as friends. I also have a girlfriend that is just right for you.”

In this example, you are letting him know that your intentions with him are platonic in nature.

You are also giving him another option by letting him know about your girlfriend.

Here, you have made two offers.

You have offered friendship and an introduction to one of your girlfriends.

What he chooses to do is up to him.

Nevertheless, you have conveyed a clear message that you aren’t interested in him romantically.

If you don’t want to verbally tell him you aren’t interested, use nonverbal language.

To do this, avoid making eye contact with him whenever he is in the vicinity, while maintaining significant physical distance from him.

Never flirt with him or give him compliments.

Eschew romantic discussions with him and keep conversations to an absolute minimum.

Using a nonverbal body language tactic in conveying the message you aren’t interested takes longer to have an effect.

It takes him a while to finally get it.

The verbal route is quicker.

It’s up to you.

Figure out what works best for you.
