He is so attentive when he is with you but rarely communicates when you are not with him.

This has much to do with him seeing other girls.

Time is being allocated to each individual girl.

There are good odds you aren’t the only girl he is giving this treatment to.

When he is with each girl, he gives them his undivided attention but then he has to move on to the next and he only has so much time in the day.

Therefore, he can’t keep you all happy with his attention all at the same time.

You don’t offer him much outside of what you do for him when he is with you.

In other words, although you are someone he is attracted to, you are not someone that he enjoys talking to when you two aren’t face to face.

He believes that the conversations tend to be boring or monotonous, as you talk about the same thing over and over.

When he is physically with you, he handles this.

Nevertheless, when he isn’t physically with you, he feels like he doesn’t want to put himself through the process of having a boring conversation with you.

He believes you are not open to doing things outside of your comfort zone.

He enjoys engaging in distinct activities that he knows you aren’t a big proponent of.

When he is not with you, he is involved in those activities and as result, he doesn’t think about you.

While he is in his element, he is engaged and you don’t cross his mind.

Furthermore, he looks at you as a casual partner or relationship.

There is a big part of him that doesn’t see you as someone that he is dating for the long term.

You are short-term fun for him.

A guy who is considering being exclusively with a girl for a long-term relationship wants to talk to her frequently.

He sees a future with her and he communicates.

He does this wanting to maintain a connection and build rapport.

Simultaneously, he doesn’t want anyone else to get in-between the two of them.

He doesn’t want to risk losing you.

In this case, rarely hearing from him when he is not with you is a sign he isn’t afraid of losing you nor interested in building rapport.

This means he doesn’t see a future with you.

Additionally, there are some guys who aren’t ready for a relationship at this moment in life.

You rarely hear from him when you are not together, being that he doesn’t want a serious relationship with anyone.

This means that you have to figure out what you want and how important that is to you.

Should you want a serious relationship and he is not prepared to give it, this isn’t beneficial to you.
