Jealous or not

So my boyfriend works at a gym with this girl and they are like buddy buddy kinda.. and she has a daughter she’s 5 anyways she’s always like “my daughter loves him” “my daughter was so excited to see him today” and my SO picks her up holds her and like plays with her like it’s his own kid. The moms always like “she loves you” and like they like hangout at work a lot.. idk tho would y’all care or nah?

Update: definitely not mad at the little girl at all just don’t like her mom.. she knows who I am she knows we have been dating for a long time. I totally thought I was kinda being dumb but you guys telling me y’all would be kinda mad too makes me feel like ok I need to talk to him about it.. but yeah and she ALWAYS says it when I’m around. Like today again “I brought her today she wanted to see you and hangout with you” and like when my man holds her and hangs out with her the mom gets those eyes like “ omg 😍) I fucking hate it.
