don't make your decision so soon..... observe him for a longer period...you need more time to think about it. You have kids, it's hard to rebuild another relationship and you can't gurantee your next man won't be like this. I know it is very likely he will do it again. How much trust that you think you can have for him after this AND how much that you love him is crucial. You are the only one that can answer this. Be strong and fight.
