I've been separated from my ex for over 4 years. Up until the last fortnight he had been having regular contact with our two sons every TH and F evening and alternate weekends. Over the course of the 4 years, he has had relationships with 3 women and the boys have been introduced to these women as "friends" he says. I was not nor did I expect/wish to be introduced to any of these women, in fact I wish the boys had not been in contact with them, but my wishes were not considered. I did not feel the need to enter into any new relationships for over two years after I split from my ex and when I did meet my current boyfriend who also has children, we were both insistent that the children were not involved in our relationship until we were sure that we had a future together. We didn't tell them that we were a couple until over a year had passed. I told my ex about my new boyfriend after 3 months. He initially said he was pleased for me and said that he'd like to meet him for a coffee. I thought this a bit strange and unnecessary and my new boyfriend did not want to meet my ex. My ex kept on at first asking at intervals claiming it was because our sons kept mentioning my boyfriend. He then started to demand and insist upon a meeting until recently he claimed that I was forcing him into a situation where he was prepared to be a non parent and not see his children unless he met my new partner. He claims that as a parent, it is his right to decide who his children see/spend time with when they are with me. Surely he is being totally unreasonable and controlling? How can he just decide to not see his children?
