is this normal?

so ive been low/to virtually no contact with narc husband. hes abusive. ( to me only, never in front of child) child stays with him and full time nanny and i live 200 miles away. i see her whenever i want, he is not being jerky about that, however, for the most part, child rarely calls, and i feel very uncomfortable calling over there but when child calls from the home ( my former marital home) my heart starts beating and i get a dry mouth, i get very anxiety ridden when she calls, but she doesnt know that. i always have my father with me during the child swap and since the last time he hit me, and i left ( hes a cop)i have never been alone with him. we sort of have a peaceable truce ( somewhat) when we make the child swap i get very anxious, nervous, etc. once i am out of his sight and with our child i am fine. i don't want to get back with him or anything like that. i just have an overwhelming anxiety, even when she talks about stuff they are doing at home and it involves him and the OW. this does not affect my visists and she will be here all summer with me and my parents. does anyone else get anxiety from dealing with their child when the child is with the narc? this feels so weird. i talked with her for an hour. she is 5.
