Bf going to his baby’s mother graduation?

Long story short. We just had a disagreement a week or so ago and wasn’t talking for a few bc he lied about going out w her and his son and her dtr. We made up he said he would be honest but today says this

I feel like since u pleaded to make it work, u kind of wouldn’t be doing the same thing over again. Sounds like I’m just getting picked over. It just seems weird then again idk any healthy Bm & BD relationships but this scenario doesn’t have anything to do w the kid
