I've been separated for three years, I have two amazing teenagers who live with me. Ex is volatile, lives with his elderly parents and has issues, not moving on with his life and I am still heavily reliant on him financially. I told him I was in a relationship in August, he reacted very badly with threats and some violence. I have been very careful to play down my new relationship to keep things smooth for my girls. My new partner is very much a part of my life, and my daughters, and they get on well, although his children don't talk to me at all. My new partner has now given me an ultimatum - that he meets my ex and things are more 'official' or he will leave me. I'm scared of losing what financial stability I have, and of the conflict that will follow, but I also don't want to lose my new partner. I think I know what I must do, but I'd really like to get the views of someone else please.
