If you aren’t a workaholic yourself, you may find it difficult to sustain this kind of relationship.
If you have a good amount of free time on your hands outside of work, you could become very dissatisfied with the fact that the person that you are dating is at work and not hanging out with you.
People don’t always fall in love with each other at the same time despite how much one party may want that.
If you haven’t been dating this guy for long and you already know that you love him, he may get to that point as well. He is a unique individual that will respond to you in his own unique way.
