Is it a big thing ?

So I was best friends with this girl I’m 22 snd 4 months pregnant and she is also 22 her name is maría and we are no longer friends anymore for about three months i havnt spoke to her and my boyfriend knows this, my other friend Ryan who is also knows Maria messaged me saying that my boyfriend reacted to her story on Instagram with the emoji “😂” is this something to confront him about? And if so how

If the roles were reversed it would be a whole different story ? Any advice
