What if I'm in love with my best friend and it's kinda complicated?
It does sound complicated. Do you what your friend is thinking?
I don't know yet.
When you have a close friendship, it is normal that you feel a mix of emotions. It isn't out of the question that a friendship could turn into a romantic relationship when you spend a lot of time together. You should talk with your friend and explain what is going on and see if his or her feelings on love are reciprocated or not.
Yeah, you are right, I think I'll talk to him about it.
Good I am glad that you are letting him know how you are feeling. Relationships can be complicated sometimes since feelings grow or fade away, so to handle that it is better to be clear.
