HELP. Is my man cheating??

Audrey
So I can be kind of a crazy bitch (we can all relate) and I was snooping on my boyfriends social media and looking at everyone he follows. Backstory- we have been dating for almost 4 years and we have a 10 month old together. Anyway, I find him commenting a lot on this girls pics. She's Canadian so I don't have to worry about him actually sleeping with her but idk if they send pics or anything. Here's a pic of one of the messages I found. I created the fake account and asked him where his baby's mama was and he's telling people we aren't together?? What could this mean? Has anyone been through this?
