I feel like an asshole

Ive been withmy boyfriend for almost two years, he is an amzing person, we have similar interests and he is so kind to everyone and caring and he treats me like a queen.

About six months ago we had some issues and I started hanging out with my best (male) friend a lot because i just wanted to rant out to someone and he is a really good listener. Four months ago that friend left for a year abroad on the other side of the world. The issues with my bf were solved and everything was fine.

Lately ive been missing that friend too much, like wayy too much, to the point in which i am doubting if I dont feel something more for him. I think about him all the time and I really do not even understand what im feeling or why. I extremely confused and Im not sure what to do. So yeah. I just needed to put it in words somewhere so here it is.
