I have a crush on my boyfriends best friend
What is it about your boyfriends best friend that makes you have a crush on them.
He is just very good looking really. He is also very nice to me.
If you are not interested in being with your current boyfriend then you need to break up with him. You are not being honest with your boyfriend. If your boyfriend suspects that you are interested in his best friend, he will break up with you first.
If I tell him I'm not going to be in a relationship with him. He will cry and complain about me doing all this just to hurt him.
If you feel yourself crushing on your boyfriends best friend than you are better off ending things with your boyfriend. This shows that you are not serious about your boyfriend, and if you act on these feelings while still being in a relationship you are going to just hurt him.
