Hi, we've been separated for almost 2 years. I kicked him out because of various reasons including taking drugs. He now has a new partner. I haven't been told about her but I found out by snooping on Facebook. The children have now met her twice. What is the normal 'etiquette' with exes and new partners. I feel I should know more about her as she is spending time with my children. Or he should at least let me know that he has introduced her to the children. Or am I being unreasonable about this and just let them get on with it? It looks like they have been seeing each other for a year. The children are 5 and 3 and she has been introduced as a 'friend'. Thanks.
