I have been with DP for 7 years. He has a teenage dd and I have two adult children. We don't live together but see one another regularly. My dp was married before I met him for 6 years but his exwife divorced him which he was devastated at the time. They co parent their dd well but this is what worries me. His ex is stunning and she has remarried. She never causes any issues for us and has told her dd off for being rude to me, dd told me when she said sorry to me. Why does it worry me so much, everytime she rings dp usually related to dd does it make my stomach churn. I just feel she could click her fingers and dp would go back to her. I know I am being ridiculous but it is really impacting me.
