I'm finding this lockdown really hard as the only other adult I see everyday is my ex partner as we are sharing care of our small child. He has a new girlfriend and the situation has been very difficult as she has been jealous we see each other but they don't right now as they can't due to the lockdown. I'm feeling trapped by the current situation and it's making me depressed. My ex has a new girlfriend who has been feeling insecure as she can't see him due to the lockdown but he sees me everyday due to us co-parenting our son. Last week he suggested we all have a video chat as she needs to get to know me so she doesn't feel insecure. He doesn't understand why I don't seem keen to get to know her as he says she might be involved with our son one day. Over the past couple of days some of the things that happened during our break up have been haunting me and I ended I telling him I was upset about it - such as telling me I was shit at sex. He got upset and said I need to leave the past in the past and we need to move on for the sake of our son and not mention or think about the past anymore. This morning he texted me and told me he was in a bad mood so I needed to avoid any more psycho dramas when dropping off our son. When he arrived he said we wouldn't be getting back together. He totally missed the point that I don't want to get back together, it's just seeing him every day and only him is dragging back all the horrible memories of our break up and that I have no other support right now. I find it hard to just forget the past and not let it affect how I behave around or feel towards him. I also don't feel comfy with the idea of getting to know his new girlfriend right now. Am I being unreasonable?
