My ex has had a bit of a whirlwind relationship and is engaged. Our teenagers stay with him and his fiancée some weekends when they aren’t busy. I hadn’t met his fiancée until recently when she decided I needed to meet her. Wants us to message, converse etc about the children. But I don’t think it’s necessary. They are teenagers with phones/lives of their own. I’m not interested in who my ex is with etc. My children can communicate their own needs. Anyone been through similar? Ex is a bit of a pushover I think when it comes to his fiancée and does what she says. We split a long time ago.
