Long story short, separated for 2 years, 2 dcs 6 and 3, ex moved out of his flat last June to move in with new girlfriend, kids had never stayed overnight with him as I said I would be happier if they got to know her first. Last Sept he sent me an email to say he was really unhappy and wanted to move out and asked me to give him money to put down a deposit on a place I said i don't have any money for him and don't want to remortgage whilst kids are so young. Three weeks ago he told me he has moved out into a new flat and gave me the address. Weird thing is for the last few Saturdays he has had kids he takes them back to his girlfriends house, they now think he has two houses! I said if he wants them to stay overnight I need to know where that will be and with whom, is she his girlfriend or what. I don't care what he does but I need to know what is going on as kids seem confused. If I had a man in my life I would tell him out of respect as he is their Dad. Am I being unreasonable?
