msinfiniti, I'm sorry for all you are going through right now. So many hurtful things for you and your son.

Can you and your husband go to a family therapist together for some marriage counseling? Maybe this would help the two of you decide on whether you want to stay together and work on your marriage or to proceed with divorce. Counseling can also help you and your husband improve your communication. That will help no matter if you decide to stay together or not.

It is possible your husband will serve you with divorce papers. You have your own attorney. Discuss this possiblity with your attorney and make sure you are prepared to be served. There really is not a huge disadvantage to being served if you are prepared for it. The shock is hard to take, but you already know it is a strong possibility.

Is the marriage with your husband and his affairs and moods the best environment to raise your son in? Remember, it is not just you who has to tolerate his instability. How is this affecting your son and is it worth it to stay if the situation does not improve? Does your husband feel any ties to your son? Does he visit now that you are separated? Is he a father in any way to your son?

Best of luck to you, msinfiniti.
