It siMply depends upon your feelings..after reading your post some important conclusive points are:
...it is not like you dislike your boyfriend now,but you still love him.
...you dont see that guy as your future husband or your dont have such feelings for him.
... Your feelings for him indicates that you want him as a friend.
All the above points are clear and does'nt indicate any fakeness or anything with your boyfriend....
It is not necessary that you have boyfriend and you can't like some other persons character..it is just a quality which gives you a good feeling on seeing him as far as you are happy with your boyfriend... IMO ...it is just a normal thing as one of your solid point is that "i am happy with my boyfriend",with this thing in mind you can like anyone's behaviour or quality and there will be no effect on your relation..best of luck ahead..
