Why is my ex posting so many selfies now?

Anonymous
Before and while we dated, he never posted any selfies of himself. We have a LOT of mutual friends because we used to work together.

Well, one of our mutual friends keeps telling me that he recently started posting a lot of selfies to his Snapchat. One of them said “happy birthday” the day of our daughter’s birthday even tho he’s never met her or tried to meet her. And every time he posts a selfie, which is often, she tells me about it. I don’t ask her. But she’ll randomly message me and I just say “ok”. She’s currently dating his brother. And randomly said “I wonder if he’s posting so much to get someone’s attention”. I assured her it wasn’t for me since we broke up January of 2020. It’s been over a year.

Does any of this sound like odd behavior? Like did he expect to me see the “happy birthday” snap on our daughters birthday? And all his terrible selfies? We haven’t talked to each other since last year.
