In my own opnion, I feel the daughter is getting emotionally tortured. It is not right for the dad to keep showing her new women everyday. This communicates a lot. The daughter might grow up thinking the dad is a womanizer and this could be the probable cause of their divorce with the mum. This will therefore bring a bad attitude towards the father as the daughter grows. My advice is simple, let Natalie sit down her ex husband and tell him whatever he is doing is going to affect the child as she grows up. It will bring emotional torture. Let him first settle himself and get one woman to be with and then he can introduce this particular one to the daughter. But on the other hand, Natalie should first find out the current condition of her daughter. Is she being affected so much or not. But am so sure, she is being affected. Thanks for sharing @nomad-magus
