Newly single mom coping

So I have been struggling lately. Me and my former partner have been separated for months and finally I told I could no longer bear to be together. I love him but our relationship is toxic and we have two different views on lifestyle and parenting. We are completely opposite he is extrovert I’m a introvert. We both are in tears discussing our relationship. He begs me to stay but I’m no longer happy. I’m afraid that our friendship and co-parenting will be destroyed. I don’t like confrontation and try to keep the peace but can no longer keep living a lie. I can not sleep or focus. I’m in a constant state of anxiety and do t have many friends I can call for support .
