Dealing with a break up

Jessica

Ok so me and my babydaddy broke up after 4

years of being together and I told him he had to leave cause us staying together in the same house hold ain’t good for us or the kids but he’s finally moved out and I have the kids but he now lives with the same girl he cheated on me with‼️‼️ I’m extremely hurt by that and it’s like my mind keeps replaying everything I’ve seen them do...how do I deal with that? How do I fix it? What steps Do I take to get over him? I know it’s not easy but I really need help/advice on this cause it’s driving me bonkers‼️‼️‼️
