How to Cope with Divorce Stress and Parenting Challenges?

Ladies I’m at my breaking point/rock bottom 😞. After years of cheating on me my soon to be ex husband told me he wants a divorce. I don’t mind giving it to him as I have been unhappy for a long time but we have 3 year old twins that don’t understand. He initiated the divorce but won’t leave the house. I don’t have a lot of money due to losing my job back in Maybecause of Covid. So I can’t leave right now and why should I have to uproot my twins?? I’m just getting back on my feet. He stays gone all day and comes in at night just to leave early before the kids get up. I get them dressed take them to school and pick them up. I’m tired and don’t know how much more I can take. Tonight I feel like I am about to have a heart attack. My chest hurts so bad and I know it’s stress. I don’t know what to do I feel like I am about to explode😩😭. Prayers please
