My boyfriend love reacted another girls pic?

I ended up on a friend of his (super pretty friends) pic who has been friends with for a long times profile and noticed he love reacted to her profile pic on march 22nd... uhh shouldn't that only be for me? I wouldn't have cared if he liked it but he barley ever reacts to anything just "likes" stuff of mine... what should I do and how so I bring it up since it was days ago?
