Am I just being extra & hormonal?

So I know she’s a celebrity and all but I honestly feel some type of way he’s calling another woman no matter who she is, his wife. Yet he says he wants to make me his wife one day but yet here we are 7 years later, 2kids and still nothing. I am also 3 weeks pp so idk if it’s just my hormones causing me to feel like or what. This just really bothers me

EDIT; he’s currently 26 going on 27 this year. Reason I stick around is I’m so used to him he feels like home now & he is a great father just horrible boyfriend which sucks cus I want to spend rest of my life with him but nowadays I even question it cus small things like this add up causing me to push away.
