You should NOT. To do so would be disloyal to your friend and you will risk losing her. Would you like your friend to do to you what you are considering doing to her?

Maybe your friend really likes this boy and doesn't do more than hold hands due to certain principles or because she needs time.

Give it time. If their relationship isn't meant to be, they will break up without YOU being the reason. And the boy will come after you himself if he really likes you.

That way you'll know he really cares and you won't be to blame for their break up.

Think. It's not worth losing your friend for any boy. So pls do the right thing and stay out of their relationship. Say nothing.

If you two are meant to be, it WILL be. In time.
