Am I wrong for this?

So basically let's call my friend "25" When we were 3rd grade I have a crush on this boy so I told my other friend. Let's call her "16" I told her because if she told me her crush I told my crush and she did but I was embarrassed to tell her , but I told it anyway. It wasn't a big deal till 4th grade or 5th grade when me and "25" were talking and I ask her about her crush because she never told me and then she wisper to my ear and is my crush name . My reaction was like "oh okay good for you" because I know my friend deserves him because there are cousin and she like him since kindergarten. My other friend ,let's called "4" she like him to and she DESERVES him because they like each other and they been a couple a few year ago. I don't know I want to forget about him and I can't so like this thing have been part me . I think like I shouldn't do that to my friends.If know it i wouldn't do that. I SWEAR I DIDN'T KNOW !
