I am still living with my ex partner of 12 years. He is waiting for his house sale to complete. I ended our relationship 9 months ago as it had been on/ off for many years he would always leave me and then beg for another chance but long story short he still isn’t over me. I have been seeing a new man for 6 months. He has got wind there is a potential SO and now he is telling me I may as well been having an affair and he thought there was more courtesy. I have politely told him that what I do/ who I spend time with/ where I go is something I will not be discussing with him. We have three children together so will be in each others life forever really but I can’t help but feel bad but I know I’m not doing anything wrong I’ve never flaunted the fact I’ve moved on I’m very respectful I’ve never had the new man in our home. Also when we were together he didn’t treat me with care or respect so he lost me and now he is saying I have taken everything from him. The new man is showing me what a healthy relationship looks like. I have tried having a normal conversation with my ex to ask if he is contributing to buying our children’s school uniform but he won’t speak to me. Should I tell him the truth or leave him wondering I just feel he will use it against me. I only see this new man when my ex spends time with our children.
