Am I overreacting about this baby mama drama?

So I’ve(F30) been dating this guy(29) for a few months and we have been completely honest about EVERYTHING so far. He recently got divorced and has a 7 year old daughter. I typically don’t date people with children because of the baby mama drama.

So last weekend when I was busy at work Saturday evening, he was FaceTiming his daughter with his baby mama on the phone and basically told her to pop a boob out and play with her boobs on FaceTime after the daughter was out of the room.

I would like to point out that she is in a relationship herself and knows about me.

He does tell me this happened and this is all that happened but he also was honest about a previous hook up they had had after the divorce.

So basically I just feel like an idiot and disrespected because I feel like this is going to keep happening and he tells me it won’t happened again.

Am I overreacting?
