Advice please!

Me and my ex have been split up for a year and a half and we have a daughter together. He doesn’t see her consistently like we had agreed when we split he would see her over the weekend as he works during the week. He was quite controlling when we were together and that behaviour had continued even though we are split. He has now told me that if/when I get a new partner that he won’t allow this man to be part of our daughters life! Of course I wouldn’t be introducing any man to my child’s life until I knew he was a good decent man etc and she is obviously my first priority. But he is insisting that no man will be part of her life! He is being totally unreasonable,right?

Ps I would have no issue with him having a new partner and her being part of my daughters life.
