When my boyfriend is free, he goes out to travel with his girlfriend who doesn't work much. Is it because he wants to travel or because he loves his girlfriend and spends all his time with her?

This matter still loves his girlfriend in essence.

Whether he likes traveling or not needs to be analyzed from two aspects.

In the first case, he may still like to travel, so he takes his girlfriend to travel.

The second situation is that your boyfriend doesn't like traveling very much, while his girlfriend likes traveling, so he also travels with him in order to be with his girlfriend.

In the world of love, companionship is the most important.
