Could I have some advice on this? My ex partner who I separated from in April last year entered into a new relationship in Oct last year and told me in the Nov. I have asked him not to introduce the baby (she has just turned one) to his new partner until they have been together a year. I've made this decision based more on the person he is than who she is. Am I being unreasonable? I will be applying the same restriction should I meet someone.
