Treese, I am sorry. Looking for positives here,at least the waiting is over. You / he know what he/you have to deal with. He did show some emotion and that he has been thinking/worrying about it for along time. I am not sure if you have a financial separation in place or how it will affect any future settlement for you and your children. I guess the sueing comment was made in the heat of the moment as it would appear he has no more money.
Treese at least you know you have been through the worst and there will be no more bombshells. You survived. What is done is done,the child cannot just disappear. Take some time for you now, try to let it go for a while at least whilst you regain your strength. It is H's problem and it sounds like he intends to deal with it (extra hours working). I know it will affect you all to some extent just try to look after you and yours. Really don't know what else to say? I guess H has a point about loosing his job, that would not be in anyone's interest. There are no winners in situations like these. You have your job and your children. Let your H deal with his problem. Step back for awhile. You are working on emotional overdrive and need to be concerned about your own health. Hugs to you Treese.
