I'm crushing hard on my wife's friend, is it even normal to do this?
Does your wife know about these feelings? Is it for real?
I think she has her suspicions.
It's not right to have a crush on your wife's friend. These feelings could end up disrupting your marriage. Control your feelings for this person.
It's my wife's friend, it's not like I'm going to do anything with her.
You have to draw the line somewhere, and to crush on someone openly enough for your wife to suspect anything then you are not being discreet enough. Be faithful to your wife, that is why you had vows.
