Ex-husband and I have been separated for over 6 years, cannot afford a divorce at this time. He's been in a relationship with a very nice lady for over two years, they don't live together, I am single by choice. Due to severe anxiety, I may be overthinking this whole thing:
I have an issue and my family doesn't think it's important.
We co-parent our 2 DD and every other weekend is spent with each parent.
I don't drive yet so their dad brings them to mine.
Recently, he's started bring his gf with him to drop them off, she has since become quite comfortable with accompanying him more frequently. Admittedly, she has remained in the car while he brings the girls bags in, but I have taken to remaining in the house so I don't have to see her when this happens.
The first time, he brought her (without asking me if it was okay), I was too shocked to say anything, I am very uncomfortable with this level of familiarity, especially as I would never invite anyone I was seeing to his house without his permission, but I don't want him bringing her to my place. The other weekend, she got a new car and, with my ex, drove over to mine to show my kids her new car, on my weekend! I think this is inappropriate and I asked my family for advice on how to stop him doing this.
Their reaction was concern about the ex's reaction and if I can just put up with it because I cannot reasonably stop him.
