Is this wrong for him to do?

Ok so there’s this girl who is one of my besties and she has a boyfriend who last year left he for me and my friend was ok with it but recently I broke up with him and he got back together with my friend and I have a boyfriend now so today he added me on Snapchat and I sent a streak with a

picture of me on it and he looked at it and said damn I look good, is that wrong for him to say if I’m his ex and he’s dating my bestie who was at one point his ex too?
